Epigenetics - Wikipedia
WEBIn biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [ 1 ] The Greek prefix epi- (ἐπι- "over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of ...
What is Epigenetics? The Answer to the Nature vs. Nurture Debate
WEBFull Text of the Graphic. “Epigenetics” is an emerging area of scientific research that shows how environmental influences—children’s experiences—actually affect the expression of their genes. This means the old idea that genes are “set in stone” has been disproven. Nature vs. Nurture is no longer a debate.

WEBEpigenetics is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes. Epigenetic change is a regular and natural occurrence but can also be influenced by ...
