Epigenetics - Wikipedia
In 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
“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.

3 days ago · Epigenetics is an emerging specialism within the field of gene study that considers an alternative blueprint for human development – one that is influenced by both genetic and environmental factors. In this guide, we’ll explore epigenetics and examine why it is becoming increasingly influential in helping us understand gene activity. We ...

Accordingly, epigenetics may have potential in the prevention, early detection, and treatment of cancer. Epigenetic mechanisms The three main epigenetic mechanisms described here – DNA methylation, histone modifications, and non-coding RNAs – have been studied primarily in the context of regulation of gene expression.
