Epigenetics
... What is epigenetics? Epigenetics refers to genetic factors that change an organism’s appearance or biological functions without changing the actual DNA sequence. In other words, gene expression changes but the genes themselves don’t. Epigenetics adds an additional level of complexity to the genetic ...
