Unlocking Optimization with Genetic Algorithms 🌐🧬 Genetic algorithms are powerful optimization techniques inspired by the principles of evolution and natural selection. Imagine a digital world where algorithms evolve and adapt over generations to find the best solutions to complex problems. Genetic algorithms mimic this process by generating a population of potential solutions, evaluating their fitness, and iteratively evolving towards optimal solutions through genetic operations like crossover and mutation. These algorithms have found wide applications in various domains, from engineering and logistics to finance and data science. They excel at solving complex, multi-dimensional optimization problems where traditional methods may struggle. By harnessing the power of genetic algorithms, businesses and researchers can unlock new levels of efficiency, cost-effectiveness, and innovation in their processes. 🚀💡 #GeneticAlgorithms #optimization #NeuralNetworksTeaser #multivariatecalculus #multivariablecalculus #differentialequations #deeplearning #neuralnetworks #datascraping #linearalgebra #vectorcalculus #dataengineering #dataengineer #differentialequations

When I thought about analyzing DNA, in my head it was gonna be all about 3D models, but all I see are letters and curves 🥹 #dna #molecularbiology #bioinformatics #microbiology #unholy

This animation shows how the proteins augmin and gamma-TuRC facilitate the branching of microtubules, thereby expanding the overall microtubule network.

🦠 From DNA to Protein: A 3D ANIMATION! This animation visualizes one of the most fundamental processes of life: how information stored in DNA is used to build proteins. The video begins inside the cell nucleus, where DNA is stored. A specific gene is selected and copied into messenger RNA (mRNA). This step shows how the DNA code is read and rewritten into a form the cell can use — without the DNA itself ever leaving the nucleus. Once formed, the mRNA strand exits the nucleus and moves into the surrounding cytoplasm. Here, it encounters a ribosome, the molecular machine responsible for protein production. The ribosome reads the mRNA sequence step by step. As it moves along the strand, transfer RNA (tRNA) molecules bring in the correct amino acids based on the genetic code. These amino acids are then linked together in the exact order dictated by the mRNA. As the chain grows, it begins to fold into a specific three-dimensional structure, forming a functional protein. This final shape determines what the protein will do — whether it supports cell structure, enables chemical reactions, or carries signals. Every movement shown in this animation represents interactions happening constantly inside living cells. This is how genetic information becomes physical matter, turning code into function and instructions into life.

EPIGENÉTICA: O Controle Sobre os Genes Além do DNA A epigenética é o estudo de alterações no funcionamento dos genes que não envolvem mudanças na sequência do DNA. Enquanto o DNA carrega as informações genéticas que herdamos de nossos pais, a epigenética determina como, quando e onde esses genes serão ativados ou desativados. Em outras palavras, é como se o DNA fosse o "hardware" e a epigenética o "software" que controla como ele é usado. Como a epigenética funciona? A epigenética opera por meio de mecanismos que regulam a expressão gênica. Os principais processos incluem: 1. Metilação do DNA: Pequenos grupos químicos chamados grupos metil (CH3) são adicionados ao DNA, geralmente desligando os genes. É como colocar uma marca que impede que o gene seja lido. 2. Modificação das histonas: O DNA é enrolado em proteínas chamadas histonas. Alterações químicas nessas proteínas podem tornar o DNA mais ou menos acessível para leitura pelos maquinários celulares. 3. RNA não codificante: Moléculas de RNA podem interferir na produção de proteínas, regulando a expressão de genes. Fatores que influenciam a epigenética: A epigenética é altamente sensível ao ambiente. Fatores como alimentação, estresse, exposição a toxinas, exercício físico e até o envelhecimento podem modificar o padrão epigenético. Essas alterações, em alguns casos, podem ser transmitidas para as próximas gerações. A epigenética e a saúde: Alterações epigenéticas estão associadas a diversas condições de saúde, como câncer, doenças cardíacas, diabetes e transtornos psiquiátricos. Por exemplo, padrões anormais de metilação do DNA podem desativar genes supressores de tumores, contribuindo para o desenvolvimento do câncer. Epigenética no cotidiano: Um dos conceitos mais fascinantes da epigenética é que nosso estilo de vida pode moldar nossa saúde e a de nossos descendentes. Por isso, adotar uma alimentação balanceada, evitar o estresse crônico e praticar exercícios pode impactar positivamente nossa expressão genética. Continua nos comentarios 👇🏼.

I want novel mutations to my protein!! Here I’m performing a quikchange expeirment. I’m introducing a DNA mutation into the DNA that encodes my protein of interest. I designed forward and reverse primers that have instructions to introduce my mutation at the correct location in my protein’s DNA sequence. I can check if my DNA mutation was successfully made by performing a bacteria transformation with this quickchange reaction material, plucking a few colonies, performing a miniprep experiment, and finally sending samples for DNA sequencing and analyzing the sequence! Isn’t it so cool that scientists have figured out how to get the DNA sequence from a small drop of a DNA sample! #phd #womeninstem #research #science #dna

💬 Comment “DNA” to get notes on DNA Replication! 🧬✨ Ready? Let’s make replication feel like a fun mission, not a boring chapter 😄👇 🧠 DNA Replication = The cell’s “copy & backup” before division ✅ So both new cells get the same genetic instructions 📚🧬 ⸻ 🚪 1) Start Point: Origin of Replication 📍 Replication begins at specific spots called origins → DNA opens up from here 🔓 🌀 2) Unzipping the Helix 🧩 Helicase = the zipper opener 😮‍💨➡️ It breaks hydrogen bonds & creates a replication fork 🍴 🛡️ SSB Proteins hold strands apart like clips 🧷 so they don’t re-join! ⸻ 🧱 3) Primer Setup (Because polymerase needs a start!) 🛠️ Primase lays down a tiny RNA primer 🧷 Think of it as the “start button” ▶️ ⸻ 🏗️ 4) Building New DNA (5’ → 3’ only!) 👷 DNA Polymerase adds nucleotides using base-pair rules: 🔸 A ↔ T 💞 🔸 C ↔ G 🤝 ⚡ Leading strand = smooth continuous build 🛣️ 🐢 Lagging strand = built in pieces (Okazaki fragments) 🧩🧩🧩 ⸻ 🧼 5) Clean-up + Joining 🧹 Primers removed & replaced with DNA 🔁 🧷 DNA Ligase = the glue gun 🔫✨ It seals Okazaki fragments into one continuous strand 🧬✅ ⸻ 🎯 Final Result (Super important!) ✅ Two identical DNA molecules Each one = 1 old strand + 1 new strand 🧬♻️ That’s Semi-Conservative Replication 💡 🧠💬 Quick quiz (comment answers!) 😄 1️⃣ Which enzyme “unzips” DNA? 🔓 2️⃣ Which enzyme “glues” fragments? 🧷 3️⃣ DNA is built in which direction? ➡️ 🎥 by yourgenome(yt)

Antibody binding to cell receptors. Antibodies are proteins that protect you when an unwanted substance enters your body. They are an important part of the body’s defence system.

The technique I’m using is called Plasmid Miniprep. It’s a fast and efficient way to isolate plasmid DNA from bacteria, which is essential for other procedures like cloning, sequencing etc… 🧪 I was specifically extracting DNA here for cloning!

🧬 Ever heard that you get 25% of your DNA from each grandparent? Well… that’s just an average! 😮 Thanks to the genetic remix party known as homologous recombination during meiosis, the DNA you inherit from your grandparents isn’t split into perfect quarters. Chromosomes swap chunks of genes like trading cards, so the actual percentage from each grandparent can vary—sometimes 23%, sometimes 27%, sometimes more or less! 🎲🔀 It’s like genetic roulette every time a sperm or egg is made. So next time someone says you’re exactly one-quarter Grandma, just smile and say, “Close enough.” 😉 #GeneticsIsWild #DNAshufflin #MeiosisMagic #RecombinationRocks #ScienceReel #ThanksGrandma #GrandpaGenes #FunFactFriday #BiologyNerd #biology #womeninstem #science #scienceiscool #sciencefacts #molecularbiology #biologyteacher #biologyiscool #biologymajor #learnwithreels
