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 👇🏼.

Genotype is the complete set of genetic material that an organism inherits from its parents. It is the genetic makeup of an organism, and it determines the organism's traits. Genotype can be thought of as the instructions for building an organism. It contains the information for everything from the organism's eye color to its susceptibility to disease. Genotype is often compared to phenotype, which is the observable traits of an organism. For example, eye color is a phenotype, while the genotype for eye color is the specific combination of genes that determines eye color. Genotype is inherited from parents through reproduction. When two organisms mate, they pass on half of their genetic material to their offspring. This means that each offspring has a unique genotype, which is a combination of the genotypes of its parents. Genotype is important because it determines the organism's traits. These traits can affect the organism's survival, reproduction, and overall fitness. For example, an organism with a genotype that makes it resistant to disease is more likely to survive and reproduce than an organism with a genotype that makes it susceptible to disease. Here is a simple analogy to help you understand genotype: Imagine that genotype is like a recipe for baking a cake. The recipe contains all of the instructions for making the cake, including the ingredients, the amount of each ingredient, and the steps on how to mix and bake the cake. The ingredients in the recipe are like the genes in the genotype. The amount of each ingredient is like the number of copies of each gene that an organism has. And the steps on how to mix and bake the cake are like the instructions for how to build an organism from its genetic material. Just as different recipes can produce different cakes, different genotypes can produce different organisms. For example, the genotype for eye color can produce different eye colors, such as brown, blue, or green. Voiced @kaijinruh @facts_and_stuff_by_d #biology #genetics #gene #geneticengineering

The transcription and translation of genetic information are the two main steps of gene expression. During transcription, the enzyme RNA polymerase copies a gene’s DNA sequence into messenger RNA (mRNA) by pairing complementary RNA nucleotides with the DNA template strand, replacing thymine (T) with uracil (U). Next, during translation, the mRNA travels to the ribosome, where transfer RNA (tRNA) molecules read the mRNA codons and bring the corresponding amino acids. These amino acids are joined together in sequence to form a polypeptide chain, which folds into a functional protein that carries out cellular functions. 🎥 by yourgenome (yt) #cellbiologylab #cellbiology #molecularbiology #medicalstudent #biology #immunologystudent

The Language of Life: The Code Beyond Chance 🧬✨ Often, science and faith are seen as competing narratives—one based on evidence, the other on belief. But when we look into the microscopic world of a single human cell, the line between them begins to blur. In this powerful clip, we explore the sheer complexity of DNA that defies the idea of a "cosmic accident." Your body contains 100 trillion cells. Inside every single one is a four-letter chemical alphabet—a code so dense and sophisticated that it contains more information than 200 years' worth of newspapers. It isn't just matter; it’s a set of precise instructions for building you. If a computer program requires a programmer, what does a biological code of this magnitude suggest? Nature can produce many things, but it has never been observed to spontaneously create high-level, functional information. #godproject #dna #scienceandfaith #creator #faith

🦠 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.
