The publication was carried out with the financial support of the Russian Foundation for Basic Research under project No. 09-08-07118. The book vividly and clearly tells the story of a new science of general biological significance - epigenetics, as well as its individual areas. The publication provides a description of various epigenetic signals and the mechanisms of their implementation, as well as the phenomenon itself, history and concepts of epigenetics, its individual mechanisms and ways of implementing epigenetic signals in the cell. The authors of various chapters of this book are the world's leading experts in the field of epigenetics, who, as a rule, are the founders of its individual fields. The publication will be useful to a wide range of readers interested in the fundamental problems of the living world, the essence of life and the molecular mechanisms of its manifestation. According to the emerging tradition of modern Russian scientific literature, the original Russian-language printed edition is untidy translated, disgustingly proofread and contains a large number of errors, starting with the cover.
