Epigenetics is the study of changes in gene expression or cellular phenotype that do not involve alterations to the underlying DNA sequence. This field explores how environmental factors, lifestyle choices, and developmental processes can influence gene activity and contribute to various biological outcomes. Unlike genetic mutations, which involve changes in the DNA sequence itself, epigenetic modifications affect how genes are turned on or off, leading to changes in gene expression.

Key mechanisms of epigenetic regulation include DNA methylation, histone modification, and non-coding RNA molecules. DNA methylation involves the addition of methyl groups to DNA, often leading to gene silencing. Histone modification refers to the chemical changes to histone proteins around which DNA is wrapped, affecting gene accessibility and expression. Non-coding RNAs play roles in regulating gene expression by influencing RNA stability and translation.

Epigenetics plays a crucial role in development, cellular differentiation, and disease. It helps explain how identical twins with the same DNA can exhibit different traits or health conditions based on their environmental exposures. Additionally, epigenetic changes have been implicated in various diseases, including cancer, cardiovascular diseases, and neurological disorders.

Research in epigenetics is advancing our understanding of gene-environment interactions and has significant implications for personalized medicine and therapeutic strategies. By targeting epigenetic modifications, scientists hope to develop new treatments for diseases and better understand how lifestyle and environmental factors influence health and disease.
