Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence. See more DNA methylation works by adding a chemical group to DNA. Typically, this group is added to specific places on the DNA, where it blocks … See more DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access … See more Your DNA is used as instructions for making coding and non-coding RNA. Coding RNA is used to make proteins. Non-coding RNA helps control gene expression by … See more WebA.
