Epigenetics: A Journey Through Inheritance Beyond Genes

For centuries, scientists have been fascinated by the mysteries of heredity and how traits are passed down from generation to generation. DNA, the molecule that stores our genetic code, was once thought to be the sole determinant of our characteristics. However, a new frontier in biology, revealing a captivating layer of complexity beyond the DNA sequence itself: Epigenetics.

What is Epigenetics?

The term "epigenetics" was first coined in the 1940s by British biologist Conrad Waddington, but it wasn't until the late 20th century that its significance truly blossomed. Epigenetics, literally meaning "above genetics," refers to the study of heritable changes in gene expression that occur without alterations to the DNA sequence itself. Imagine DNA as the musical score, but epigenetics are the conductor and musicians who determine how the music is played. Through chemical modifications and adjustments to the proteins around DNA, epigenetics dictates which genes are turned on or off, influencing how cells function and ultimately shaping our health, development, and even behavior. Think of your DNA as the hardware: it contains the basic instructions for building and running your body. But epigenetics acts like the software, fine-tuning those instructions and determining which genes get turned on or off at specific times and in specific cells. These modifications, like chemical tags or changes in the packaging of DNA, don't alter the underlying code itself, but they can have a profound impact on how it's read and interpreted.

The Key Players:

DNA methylation: This process involves adding a methyl group to DNA, essentially silencing the gene it's attached to. Imagine it like putting a dimmer switch on a light bulb.

Histone modifications: Histones are proteins that package DNA, and changes in their structure can make genes more or less accessible to the cellular machinery needed for expression. Think of it like adjusting the curtains around a window - open wide for full light, slightly closed for filtered light.

Non-coding RNAs: These are molecules that don't code for proteins but can regulate gene expression in various ways. They're like the backstage crew in a play, ensuring everything runs smoothly.

The Power of Epigenetic Regulation

Epigenetic regulation plays a crucial role in various biological processes, including:

Development: During embryonic development, different cell types emerge from the same DNA blueprint by activating or silencing specific gene sets through epigenetic modifications.

Cellular differentiation: Specialized cells like muscle or nerve cells have unique functions due to differences in their active genes, controlled by epigenetic mechanisms.

Learning and memory: Epigenetic changes in brain cells are thought to be essential for learning and forming memories.

Aging: As we age, our epigenome accumulates changes that can contribute to age-related decline and disease.

Environmental influences: Diet, exercise, stress, and exposure to toxins can leave epigenetic marks on our genes, potentially impacting our health and even the health of future generations.

Epigenetics reminds us that we are not simply products of our genes. Our environment, choices, and experiences leave their mark, shaping who we are and potentially influencing our children's health. This deeper understanding of ourselves opens doors for self-awareness, empowerment, and potentially reshaping our narratives – not just as individuals, but as a species with the potential to leave a healthier legacy for generations to come.

Brotherhood (2)

Directly following the events of Double Helix, Danny enrolls in Bayville High school and joins the Brotherhood of Mutants. He's not sure if they actually believe he's a ghost and not a mutant, but at least they don't care enough to challenge him on it, and that's good enough for him. This is a direct sequel to Double Helix (linked above), and some parts may be confusing without the context of the original fic. I suggest you read that first.

Written for @crossoverdanuary Week 2024, Day 5: The Owl House X-Men Evolution | Shell

I have seen exactly two episodes of The Owl House, and that was like four years ago or something, so I was not confident in my ability to write a crossover for it. Also, from this chapter on, it's unedited and I'll come back to edit later. I just want to actually finish this fic tonight.

I tried to work in a theme of both Danny and Wanda "coming out of their shell" throughout the fic. You can also read it on AO3.

Chapter 2: Transition

[Warning for mental institutions]

"You guys got any plans for the long weekend?" Lance asked as he sprawled out on the shabby couch in the board house. "Kitty told me she and some of the X-dorks are going on an educational retreat to the California redwoods. They decided on it yesterday. Can you imagine being able to just up and fly to the other side of the country on a whim."

"And for educational purposes, yuck!" Toad agreed. "If I had my own jet like they do, I'd go to Vegas!"

"If you could afford a jet like they have, you wouldn't have to go to Vegas," Lance said. "You'd already be rich. If I had my own jet, I would use it to go to all the concerts I'd normally miss because they're too far away."

"I don't need a private jet to go wherever I want," Pietro bragged. "If I want to go to a concert, I'll run right in past security and no one will even know."

"And if that concert is in Europe?" Lance asked. "Or Asia? You know, across a massive ocean? Can you run there?"

"Okay, point taken, but why would I wanna go to a snooty European concert anyway?" the speedster scoffed. "What about you, Danny?"

"What do I need a jet for? I can already fly," he said. "Not that I use it for major travel much. Maybe I should. That's what my cousin does. She flies all over the world."

"Hey! We should do something fun this weekend!" Toad declared. "Maybe sneak into a concert, or go somewhere cool! Show those X losers we know how to have a good time while they use their fancy private jet to go learn things."

"Sure, I'm down," Lance agreed.

"Sorry guys, I'm gonna pass this time. I actually do have plans this weekend," Danny said. "I'm gonna fly upstate and visit a friend. I haven't seen her in a few weeks."

"Her?" Pietro repeated with a smirk. "This wouldn't happen to be a girlfriend would it?"

"It's not like that," Danny said. "She's a friend. She's a girl. That's it."

"Uh-huh... sure," Toad said, sounding unconvinced. "You dog."

"Lay off," Danny said, rolling his eyes. "Come on, we gotta get to school. Long weekend's not here yet."

Toad groaned.

"Buck up, we've only got one more day," Lance pointed out.

When the long weekend finally arrived, Danny filled his pockets with all the things he wanted to bring, said good-bye to the Brotherhood, who barely acknowledged him as they argued about what to do that weekend, and took off. He flew north, toward the mental institution. It had been almost three whole weeks since he'd last been there, but he remembered the way.

Honestly, he hadn't expected to go back so soon, and Wanda probably wouldn't be expecting him either, but it wasn't like he was gonna be an inpatient this time. He would turn invisible and pop into Wanda's room to hang out with her. It hadn't even been that long, really, but he missed her.

Thinking about her in that room all alone again, without anyone or anything to distract her, it almost made him regret leaving in the first place. He should have been more considerate. Even though she said she'd be okay, leaving just because he didn't like Xavier was selfish.

When, after almost a full day of flying, he finally caught sight of the building, resentment gripped his chest. He hated this place. If it weren't for Wanda, he wouldn't have even stayed as long as he had. And if it weren't for her, he definitely wouldn't have come back, ever. No matter what.

But he did. He came back. For Wanda.

Sneaking in went just as planned. No one saw him. No one heard him. He was a ghost, after all. The moment he saw Wanda, he realized that he'd missed her even more than he'd thought.

"Knock knock," he said as he appeared in her room.

She jumped in surprise, but when she saw him, she smiled. "You scared me."

"Should I have said 'Boo', instead?" he asked. "I totally should have. Missed opportunity."

She chuckled slightly and shook her head.

"You seem to be doing pretty well, all things considered," he noted.

She was still wearing a straight jacket, but it looked looser, like whoever had put it on her wasn't as worried about her getting out. Her small smile still seemed genuine. Three weeks on her own again hadn't sent her straight back to her darkest place, it seemed.

"Yeah," she agreed. "I've been taking your advice. Whenever I notice myself getting stuck thinking about the bad memory, I try to think of three good ones. It's hard sometimes, but I think the more effort it takes, the better it works, because it keeps me distracted for longer. Yesterday, I remembered reading that book with you. You know the one. I tried to imagine an ending for it where they were both arrested as war criminals instead of having a happy ending. Do you want to hear it?"

"Absolutely," Danny confirmed.

In truth, he hadn't even thought about that trashy romance novel in ages. It was largely forgettable for him, but if it helped Wanda better navigate her emotions then hell yeah he wanted to hear her ideas for an alternate ending.

In her version of the ending, there was a huge trial. The kings of both sides agreed that the Warlock and Sorceress were guilty of crimes against Arvenia, and sentenced them to live the rest of there lives in a deep, dark dungeon where the lovers could only communicate by having rats deliver notes between them.

Then, after years of planning their escape one note at a time, they broke out and took over the world together, killing the kings and terrorizing the people of Arvenia to keep them in line.

"Ooh, plot twist!" Danny said when she got to that part. "I like that you made them the villains in the end. They should have been the villains from the beginning."

"I agree," Wanda said. "It was stupid that the book just gave them another villain to blame for all the bad things they did and fight off, rather than acknowledging their crimes."

"Totally!" Danny emphatically agreed. "Oh, I just remembered! I brought you some stuff."

He reached into his pockets and pulled out all the stuff he'd brought. He pulled out a deck of cards, a book of MadLibs and a pen, a sheet of stickers. He wasn't sure what they would have the most fun with, so he'd just brought a bunch of random junk. Lastly, he pulled out a necklace, a black choker with an ankh charm.

"What's that?" she asked.

"Your first goth accessory," he said. "I found it in a random box in the attic where I'm staying now."

"No, I mean what's that symbol?" she asked, repositioning herself so Danny could put the necklace on her.

"Oh, it's an ankh. The Egyptian symbol for life, I think."

"Life, huh? Doesn't sound very goth."

"Well, you would be wearing it ironically," he said. "Most of the other gothy stuff I found had crosses, and seeing as your Jewish and all...." He shrugged. "Felt like it would be disrespectful. So, do you like it?"

"Yeah, I like it a lot," Wanda said. "You know," her voice became suddenly softer than before, like she was nervous. "Professor Xavier is going to come tomorrow. I think tomorrow might finally be the day he takes me with him."

"You think?" Danny asked, excited for her despite his hatred of the professor.

"Yeah," she confirmed. "I've been doing a lot better lately, and I have a really good feeling about it."

"That's awesome, Wanda!" he told her. "In that case, let's call the necklace a good luck charm. I'm rooting for you. I know you can do it."

"Thanks."

"You know, I also found this totally sweet red leather coat when I was rooting around in the attic," he said. "Ankle-length, flared collar, and it's your favorite color. Once you're ready to give up the straight jacket, I'll bring it to you as a congratulations present. What do you think?"

"I think you're really trying to motivate me."

"What can I say? I miss my friend."

"Then we have a deal," she agreed. Tomorrow is gonna be the day. I just know it."

Danny grinned widely at her.

For the rest of the day, they mostly played MadLibs. They tried a few card games, too, but with Wanda's hands restrained, the only thing they could really do was collaborative solitaire, and that got old fast. Danny stuck little ghost and bat stickers on all the latches on her straight jacket while he told her about the school he was going to, and the board house. How he'd picked the same city the Xavier Institute was in so he could see her again when she enrolled there.

"They're all mutants at the board house," Danny told her. "I don't know if they actually believe I'm not, but they don't push it. They don't even call me a mutant by mistake. I don't know, maybe it's 'cause they're afraid I'll do something, or maybe it's 'cause they just don't care enough to argue with me, but either way, that's better than I ever got from Xavier."

"I'm glad you found people who accept you," Wanda said. "I hope when I go to the professor's school, I will too."

"Me too," Danny agreed. "And hey, even if you don't find them there, you'll still have me."

She smiled at him. Her smile was always small, burdened, a little sad behind the eyes, but it was honest. Danny liked that about her. She never tried to hide anything.

That night, he crashed in her room. Despite being fully padded, it was not very comfortable, but it was better than trying to fly through the night and ending up sleeping in a tree somewhere. He said 'see ya later' and left early in the morning to make sure he wouldn't be seen when the orderlies came to get her for her meeting with the professor, and promised to meet up with her again soon.

Then, he spent another day flying back to Bayville.

"You're getting back a little late, aren't you?" Lance observed when Danny finally returned to the board house. "Did you get to spend some quality time with your girlfriend?"

"Again, not my girlfriend, but yes, I did," Danny responded. "How was your... whatever you guys decided to do this weekend?"

"Oh, we ended up not being able to decide, so we just ordered pizza and stayed here all weekend," Lance answered. "So that was... that."

"Oh, yeah, those X-Men are gonna be soo jealous of the weekend you had."

"Shut up!"

It wasn't until a couple days later that news reached the Brotherhood of the X-Men's newest member. It came by way of Lance's budding relationship with Kitty.

"Really!? The X-Men have a new member?" Danny repeated excitedly when he heard the news after school.

"That's what Kitty said," Lance confirmed. "Apparently she's not gonna start at Bayville High for another few of days so she can get settled, but yeah. I don't know anything about her, though."

"I'm pretty sure I do!" Danny said. "I gotta go!"

"What?"

Danny didn't bother to explain. He went ghost, made a quick pit-stop in the attic to grab something and then flew straight for the Xavier Institute. He'd never actually been there before, but Tabitha told him where it was a while back. Apparently, she used to be an X-Men trainee before she joined the Brotherhood, and she was still friends with some of them.

Turrets rose up out of the ground the moment he got past the gate. Probably motion-activated. Danny easily avoided getting hit by turning intangible and staying that way until he'd flown straight through the front door. It actually took a while. The grounds were huge.

By the time he got through, there was a group of mutants waiting for him, suited up and ready for a fight.

"Relax, I'm not here to fight," Danny said. He held up the paper bag he'd brought with him. "I'm just bringing a friend a gift."

"Who are you?" demanded a guy with a weird visor. Scott, probably. He seemed like Scott.

"What do you mean who am I?" Danny asked. "You know me!"

"Like, I've never seen you before," Kitty said, crossing her arms.

How they expected to protect their identities when they didn't even wear masks, Danny had no idea.

"What are you talking about? I—" He stopped himself abruptly. "Oh yeah, my bad," he said, and let the rings of his transformation wash over him, revealing his human form. "Recognize me now?"

Judging by their gasps, the answer was yes, but they didn't stand down.

"What are you doing here?" Jean asked. "I thought you didn't want anything to do with the Xavier Institute."

"I don't wanna join, but it's not like I hate you guys or anything," Danny said. "This just isn't the place for me. And I already told you why I'm here. I'm brought a congratulations present for Wanda. She's your new member, right? Or trainee? Whatever."

"How do you know that?" asked a fuzzy blue mutant that Danny didn't recognize until he started talking. That German accent was unmistakably Kurt.

"Well, when I saw her the other day, she said she felt really confident that she was going to be able to join you guys soon, and then Lance said Kitty said you got a new member, so I figured it must be her."

The others all glared at Kitty.

"What?" she asked. "It's not like it was gonna be a secret for long anyway. We, like, all go to the same school!"

"I wasn't aware you and Wanda were so close," came a familiar voice.

Danny turned to see the professor wheeling in and had to school his face to avoid scowling at him.

"We're friends," he said. "Can I see her or not? And keep in mind if you say no, I'm just gonna find her anyway."

"As long as you haven't come with ill intentions, I see no reason why you shouldn't be allowed to see her," the professor said. "We're all mutants after all, and a sense of community is important."

"I'm not a mutant," Danny muttered, his scowl finally breaking through.

The professor responded with a tight smile. "Jean, why don't you show Danny to Wanda's room."

"Of course, professor," Jean agreed. "It's this way."

She headed up the stairs and Danny followed.

"So do you and Wanda know each other from the institution?" Jean asked. "I mean, sorry, that's probably personal. I hope you don't mind me asking."

"It's fine," Danny said. "Yeah. Security couldn't exactly hold a guy who walks through walls, so I would sneak into her room sometimes and we'd hang out. She always wanted to be able to come here. I could never really understand it, but I'm still proud of her, you know? I may not agree with you guys, but you're good people. For the most part. I'm not quite sold on Scott, yet."

Jean chuckled. "I guess we can't really ask for more than that." She stopped in the hallway and knocked on a door. "Wanda, you in there? You have a visitor."

The door opened seemingly on its own.

"Danny!" Wanda's voice called. "I didn't think you'd be here so soon."

"I came as soon as I heard, and I guess word travels fast," he replied. "Can I come in?"

"Yeah, come in," she said.

"I'll leave you to it," Jean said, as she backed away into the hall and closed the door behind her.

"You look good," Danny said.

Her clothes were a bit mismatched, but it was the first time he was seeing her without a straight jacket, and that was a huge improvement. She was also wearing the choker he'd given her. Her hair looked recently washed, and was neatly combed and tucked behind her ears.

Even the way she held herself was more confident, happier. Not being in that rotten mental institution was already having a positive affect on her, it seemed.

"I brought something that'll make you look even better." He held up the paper bag.

"The coat?" she asked, rushing forward excitedly to take the bag from him.

"I hope it fits," he told her. "It looked about the right size."

She let the bag drop to the floor as he pulled the coat out and smoothly slid it on. It looked like it might be a little wide in the shoulders, but other than that, it fit like a glove.

"It's perfect," she said.

"I also found some earrings that match the necklace," he said. "I slipped 'em in one of the pockets. I know you don't have pierced ears, but I figured if you ever did, you might like to have them."

She patted the pockets until she found what he was talking about and smiled when she pulled them out. Then, she laid them gently on her dresser.

He didn't think he'd ever seen her smile so much, and so unabashedly. It wasn't the tiny, hesitant smile she'd worn before. She was really coming out of her shell.

"Careful," he said. "Looking at you now, I'd almost think you weren't consumed by rage."

Her smile fell.

That had been the wrong thing to say.

"I am still angry," she said. "I can't stop it. But... you were right. I didn't need to control my anger. I just had to stop letting my anger control me. Now I can be angry and happy at the same time. Angry and excited. I feel more than just anger now. It feels good."

"I'm happy to hear it," he told her. "So how's this place treating you so far?"

"I have a roommate!" she replied instantly. "Her name is Rahne. And tomorrow, when they're done with school, she and some of the other girls are gonna take me to the mall for new clothes so I don't have to wear stuff from the lost-and-found anymore."

"That makes sense," Danny said.

"Do you wanna come?" she invited.

"I... would... but I might ruin the mood," he said apologetically. "Some of them don't trust me since I'm technically part of the Brotherhood, and we're... enemies? Rivals? Something like that. Plus, you don't want a guy tagging along on your first girl's shopping trip. Trust me. You'll want the full experience."

"You have a point...."

"I'll enjoy the surprise of seeing your new wardrobe when you come to school in a few days," he said.

They hung out and chatted for a little while until Wanda's roommate came back and Danny figured that was his cue to go. As he left her new room, he had the distinct pleasure of telling her he'd see her at school.

He could feel eyes on him until he was all the way off the manor grounds. They may not have hated him, but these X-Men sure as hell didn't trust him either.

Whatever. He didn't care what they thought about him. As long as they took care of Wanda, and left him alone, they were alright in his book. So far, so good.

A bronze statue of a laboratory mouse knitting a double helix of DNA in order to honor all the mice that were sacrificed for genetic research to develop new drugs to fight diseases.

It was designed by Andrew Kharkevich and is located in Siberia, Russia.

The monument was completed on 1 July 2013, coinciding with the 120th anniversary of the founding of the city.

The monument commemorates the sacrifice of the mice in genetic research used to understand biological and physiological mechanisms for developing new drugs and curing diseases.

Sculptor Alexei Agrikolyansky, who created the statue, confessed that it was challenging to capture this moment, as the mouse was obviously not human.

Nevertheless, he had to produce a character with believable emotions while maintaining anatomical proportions, avoiding it looking like a cartoon character or a real mouse.

The DNA spiral emerging from the knitting needles winds to the left, symbolizing the still poorly understood Z-DNA - representing the scientific research that is yet to be done.

In contrast, the more common B-DNA winds to the right.

The very first photograph of DNA was captured by a woman named Rosalind Franklin (25 July 1920 – 16 April 1958) using X-ray technology, allowing James Dewey Watson (born April 6, 1928) and Francis Harry Compton Crick OM FRS (8 June 1916 – 28 July 2004) to accurately characterize the double helix.

While they went on to win the Nobel Prize in Physiology or Medicine in 1962, Franklin was not credited.

Sadly, she had passed away in 1958 from ovarian cancer, most likely caused by the high radiation exposure she endured while working with X-rays to capture the image of the double helix.

A snip, a splice : Power of rDNA Technology

Deoxyribonucleic acid (DNA), the blueprint of life, holds the secrets to the intricate workings of every living organism. But what if we could manipulate this blueprint, adding, removing, or tweaking its code? This revolutionary concept forms the core of recombinant DNA (rDNA) technology, a powerful tool that has transformed biology and medicine.

The story starts in the early 1970s with two brilliant scientists; Stanley Cohen at Stanford University and Herbert Boyer at the University of California, San Francisco. Cohen, a microbiologist, had been studying plasmids – small circular DNA molecules found in bacteria. Boyer, a biochemist, was an expert on restriction enzymes – molecular scissors that could cut DNA at specific sequences. Their collaboration proved groundbreaking. They envisioned combining these tools to create the first ever recombinant DNA molecule. Cohen provided the plasmids, which would act as vectors to carry foreign DNA into host cells. Boyer, on the other hand, used restriction enzymes to cut both the plasmid and the desired foreign DNA, allowing them to be pieced together. Through meticulous experimentation, they successfully created the first recombinant DNA molecule, forever altering the course of biology.

Cohen and Boyer's work wouldn't have been possible without the earlier discoveries of restriction enzymes. These "molecular scissors" were independently identified by three separate research groups in the 1960s. Werner Arber in Switzerland, along with Hamilton Smith and Daniel Nathans in the US, unraveled the role of restriction enzymes in bacterial defense mechanisms. These enzymes helped bacteria defend against invading viruses by cutting up their foreign DNA. Recognizing the potential of these "genetic scalpels," the groundwork was laid for their application in rDNA technology.

Here's a simplified breakdown of the rDNA process:

Isolation of DNA: The journey starts with isolating DNA from a donor organism.

Cleavage with Restriction Enzymes: Specific enzymes cut the DNA at defined sequences.

Selection of Vector: A carrier molecule (often a plasmid) is chosen to transport the recombinant DNA.

Ligation: The DNA fragments and vector are stitched together using DNA ligase, an enzyme.

Transformation: The recombinant DNA enters a host cell (usually bacteria or yeast).

Selection and Expression: The transformed cells are selected, and the gene of interest is expressed, leading to the desired protein production.

Since its inception, rDNA technology has played a pivotal role in several groundbreaking advancements. Let's take a whirlwind tour through some of the most significant moments in R-DNA history:

1978: Birth of Insulin on the Factory Floor: Scientists achieved a feat of genetic engineering by using R-DNA to produce human insulin in bacteria. This marked a turning point for diabetics, offering a readily available and more consistent source of this life-saving hormone.

1980s: Gene Wars and the Rise of GMOs: The 1980s saw the development of genetically modified organisms (GMOs). Plants were engineered with genes for insect resistance or herbicide tolerance, sparking debates about the safety and ethics of this technology. R-DNA research continues to be at the forefront of discussions regarding genetically modified foods.

1990s: The Human Genome Project Sets Sail: This ambitious international project aimed to sequence the entire human genome. R-DNA techniques played a crucial role in deciphering the 3 billion letters of our genetic code, opening doors for personalized medicine and a deeper understanding of human health and disease.

2000s: Gene Therapy Takes Center Stage: The first successful gene therapy trials for inherited diseases like severe combined immunodeficiency (SCID) took place. R-DNA technology offered a glimmer of hope for treating genetic disorders by introducing healthy genes to replace defective ones.

2010s and Beyond: CRISPR Takes Over: The emergence of CRISPR-Cas9, a revolutionary gene editing tool based on R-DNA principles, has ushered in a new era of genetic manipulation. With unprecedented precision, scientists can now edit genes in various organisms, holding immense potential for gene therapy, crop improvement, and even the eradication of diseases.

But with great power comes great responsibility, and R-DNA raises a host of ethical concerns.Tinkering with the building blocks of life carries the risk of unintended consequences. Engineered genes could escape and disrupt ecosystems, or modified organisms could have unforeseen health effects. The ability to edit human genes opens the door to designer babies, raising questions about social equity and the potential misuse of the technology for eugenics.

Who Controls the Tools? Access to R-DNA technology could be restricted to wealthy nations or corporations, exacerbating existing inequalities. Biosecurity is also a concern, as the technology could be misused for bioterrorism. Creating entirely new organisms forces us to confront what it means to be "natural." Should we modify plants and animals for human benefit, or preserve their original forms? R-DNA technology is a powerful tool, and we must have open discussions about its ethical implications. Scientists, policymakers, and the public all need to be involved in shaping the future of this technology. As we move forward, open dialogue and collaboration between scientists, policymakers, and the public are crucial to ensure the safe and ethical application of this powerful technology.

The journey of rDNA technology is a testament to human ingenuity and its potential to reshape our world. From decoding the secrets of life to creating solutions for healthcare, agriculture, and beyond, rDNA technology continues to evolve, promising a future filled with exciting possibilities.
