Epigenetics is the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. These changes can be inherited and are often reversible. Epigenetic modifications include DNA methylation, histone modification, and non-coding RNA expression. They play a crucial role in development, differentiation, and disease. For example, epigenetic changes can lead to the activation or silencing of genes, which can influence various biological processes such as cell growth, differentiation, and apoptosis. Epigenetic modifications can be influenced by environmental factors, lifestyle, and aging, making them dynamic and responsive to external stimuli. Understanding epigenetics is essential for advancing our knowledge of genetic disorders, cancer, and other complex diseases. Techniques such as bisulfite sequencing, chromatin immunoprecipitation, and RNA sequencing are commonly used to study epigenetic modifications.
