Epigenetics-in biology, in particular, genetics-the study of patterns of epigenetic inheritance-changes in the expression of genes or cell phenotype caused by mechanisms that do not affect the DNA sequence. Epigenetic changes remain in the mitotic compartments of somatic cells, and can also be transmitted to the next generation. Examples of epigenetic changes are DNA methylation and histone deacetylation. Epigenome-a molecular signs that regulate the activity of genes, but do not change the original structure of DNA. In the framework of epigenetics examines processes such as paramuricea, genetic bookmarking, genomic imprinting, inactivation of x chromosomes, the effect of condition, maternal effects, reprogramming, as well as other mechanisms of gene regulation. In 2011, mRNA methylation was shown to play a role in diabetic predisposition, which was the beginning of a new industry — RNA epigenetics. For example: one example of the epigenetic changes of eukaryotes is the process of cell differentiation. In morphogenesis pluripotent stem cells form different polypotent cell lines of the embryo, which, in turn, give rise to fully differentiated cells. In other words, the fertilized egg-the zygote-neurons with electronic elements, muscle cells, epitelialna, blood vessels, and so endotelialny.b. including, cells differenciate in different types. This is achieved by the activation of one gene, as well as inhibition of others by epigenetic mechanisms.
