摘要

细胞或生物体表型的变化是可遗传的,但不涉及DNA序列的变化,称为表观遗传。它们主要通过染色质蛋白质或DNA的化学修饰的获得或损失而发生。因此表观遗传学是一个非孟德尔过程。真核生物表观遗传学的研究随着对机制和表型之间关系的认识的进步以及作为多细胞性和癌症的要求而不断扩大。然而,生命也包括其他群体或领域,尤其是细菌和古菌。表观遗传学在这些深层谱系中的发生是一个伴随争议的新兴话题。在这些非真核生物中,表观遗传学至关重要,因为它激发了新的进化理论,并完善了对生物作用的看法。

Evidence of an Epigenetics System in Archaea
Changes in the phenotype of a cell or organism that are heritable but do not involve changes in DNA sequence are referred to as epigenetic. They occur primarily through the gain or loss of chemical modification of chromatin protein or DNA. Epigenetics is therefore a non-Mendelian process. The study of epigenetics in eukaryotes is expanding with advances in knowledge about the relationship between mechanism and phenotype and as a requirement for multicellularity and cancer. However, life also includes other groups or domains, notably the bacteria and archaea. The occurrence of epigenetics in these deep lineages is an emerging topic accompanied by controversy. In these non-eukaryotic organisms, epigenetics is critically important because it stimulates new evolutionary theory and refines perspective about biological action.
