Epigenetics

Definition of Epigenetics as it relates to Science, Genetics

Epigenetics refers to the study of heritable changes in gene expression and function that occur without alterations to the underlying DNA sequence. It explores how various factors such as environment, lifestyle, and aging can influence gene activity, leading to phenotypic differences among individuals with identical genetic backgrounds. Epigenetic modifications include DNA methylation, histone modification, and non-coding RNA regulation, which work together to regulate gene expression in a dynamic and reversible manner. The field of epigenetics has broad implications for understanding the development and progression of complex diseases such as cancer, diabetes, and neurological disorders, as well as potential therapeutic strategies for their treatment.
