tailieunhanh - A review on epigenetics: Importance in livestock breeding and production

Epigenetics is the study of heritable changes in gene expression and other genomic functions without altering the underlying DNA sequence. It is associated with gene expression and the expression of different phenotypes mainly by a level of genetic regulation which is independent of the DNA sequence and transmitted somatically or inherited through modification of DNA regions and allows organisms on a multigenerational scale to switch between phenotypes. Gene expression due to epigenetics is mainly due to internal and external environmental effects present around an organism and these changes play a role in short-term adaptation of individuals and include reversibility. |
