Here’s another editing function that we humans now have over our own genes. Cool advances by scientists to advance the frontier.
Epigenetics is the study of the chemical changes that happen to DNA throughout a lifetime, which in turn affect the expression of genes. These changes can occur as a result of a person’s behavior (such as through diet or smoking) or environmental exposures (such as to toxins or ultraviolet rays). Epigenetics is a kind of molecular memory that reflects the experiences that we’ve encountered over many years. It’s the reason why, among identical twins who share the same DNA code, one may develop cancer while the other remains healthy.
