Epigenetics now transcends genetics, genomics and molecular biology. It is now poised to be the vanguard of biological science. This new and dynamic discipline challenges and revises traditional paradigms of inheritance. Through epigenetics the classic works of Charles Darwin and Gregor Mendel are now seen in different ways.
As more factors influencing heredity are discovered, today’s scientists are using epigenetics to decipher the roles of DNA, RNA, proteins and environment in inheritance.
The future of epigenetics will reveal the complexities of genetic regulation, cellular differentiation, embryology, aging, cancer and other diseases.
Epigenetics is now the prominent theme in the study of human development from fertilization through aging and to death. Epigenetic markers control the expression of genes that function since embryonic development, but other epigenetic programming events occur concurrently. These include the erasure and re-establishment of DNA markers, genetic imprinting, X-chromosome inactivation, the development of stem cells and the differentiation of somatic cells.
Cancer and a host of other diseases have epigenetic etiologies and many epigenetic diseases are caused by mutations in genes necessary for chromatin structure. This is why the study of epigenetics research technique is now the forefront of molecular science.
