Epigenetics is really interesting because it helps us understand how our surroundings can affect our genes without actually changing the DNA itself.
How It Works:
Environmental Factors: Things like the food we eat, how stressed we feel, and even chemicals around us can change how our genes work.
Methylation and Acetylation: For example, when a tiny group called a methyl group (that’s 1 carbon and 3 hydrogens) attaches to DNA, it can turn a gene off. On the other hand, when another group called acetylation attaches, it can turn a gene on.
Example: Think about a child who grows up in a caring and loving home. That child might show certain strengths like being able to handle tough times well. But if the same child grows up in a stressful situation, those same strengths might not show up.
This shows how both our genes (which we inherit) and our life experiences shape who we are.
