Epigenetics and imprinting
WebGenomic imprinting is an epigenetic phenomenon resulting in monoallelic expression of a gene depending on its parental origin. It plays an important role in embryonic, fetal and placental growth as well as in neurodevelopment and postnatal development. WebOct 11, 2024 · The term “epigenetics” has been widely used and abused [1] but the most compelling definition of epigenetics is the study of changes in gene function that are heritable through cell division, yet reversible, and that do not involve changes in DNA sequence - with heritability and reversibility being the key factors. Epigenetic information …
