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? | CDC
WEBAug 15, 2022 · 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.

WEBApr 12, 2024 · epigenetics, the study of the chemical modification of specific genes or gene-associated proteins of an organism. Epigenetic modifications can define how the information in genes is expressed and used by cells.
What is epigenetics?: MedlinePlus Genetics
WEBJun 11, 2021 · Within the complete set of DNA in a cell (genome), all of the modifications that regulate the activity (expression) of the genes is known as the epigenome. Because epigenetic changes help determine whether genes are turned on or off, they influence the production of proteins in cells.

WEBEpigenetics is the study of how our environment influences our genes by changing the chemicals attached to them. What we eat, our physical activity level, access to resources and more affect those chemicals, in turn shaping our health. Epigenetics can help scientists understand why diseases happen and explore new avenues for treatment.
