Epigenetics boiled down is basically how the physical shape of the DNA strand affects its expression. For example, methylation makes it all kind of scrunch up so the DNA helicases and other enzymes have a hard time reading it, leading to it not being expressed. Epigenetics and methylation can change throughout your life time and are crucial to development.
There are many mechanisms that make epigenetic changes. Like methylation of DNA or modification of histones ex ...
