Epigenetics and genomics are fields of science that are concerned with the study of the genetic makeup of organisms. Through the study of epigenetics and genomics, scientists are able to better understand a wide variety of genetic diseases and processes in living organisms. Epigenetics is the study of changes in gene expression that are not caused by changes in the underlying DNA sequence. These changes can be passed on from one generation to the next, and they are thought to be important in the growth and development of an organism. Through the analysis of epigenetic mechanisms, the processes that lead to gene expression can be better understood. Genomics is the study of the structure, function, variation, and evolution of genomes. It is a relatively new field of study that has yielded many exciting discoveries. Through genomics, the genes of an organism can be better understood, and gene functions can be better elucidated. This allows scientists to understand how changes in gene structure, function, and expression can influence an organism's health and development. In combination, the fields of epigenetics and genomics can provide great insight into our understanding of the genetic basis of diseases and processes. By better understanding the mechanisms of gene expression, scientists can develop better treatments for genetic diseases, as well as discover more about the genetic basis of development and behavior. Additionally, because changes in gene expression can be passed on from generation to generation, research in these fields can also provide a better understanding of evolution and how organisms have adapted to their environments over time.
