Epigenetics

Epigenetics is the study of changes in gene expression, or activity, that occur without alterations to the genetic code. This is achieved by attaching chemical tags, known as epigenetic marks, to the genome to regulate the expression of genes. It is an important field of study as it can explain how organisms develop and respond to their environment. Epigenetic modifications can affect how cells divide, how they behave in different tissues, and how disease develops. Understanding thesechanges can help scientists better understand cancer, aging, and other diseases. Epigenetics are also being used to develop new therapies, as well as new ways to diagnose and treat diseases.
