| 释义 | epigenetics noun[ U ] biology specializeduk /ˌep.ɪ.dʒəˈnet.ɪks/ us /ˌep.ɪ.dʒəˈnet̬.ɪks/ a branch of genetics that studies the chemical reactions that turn genes on and off表观遗传学 Genetics accession number adenine anaphase autosomal autosomally genetic fingerprinting genetically engineered geneticist genic genomic genomics genotypic monozygotic mutate non-familial non-genetic non-mutant nondominant nonhomologous sex-linked Examples of epigeneticsepigenetics If you are searching for papers on the role of mitochondria, telomeres or epigenetics in cloning the papers are cited here in separate lists. What does seem like an omission is any specific treatment of epigenetics or epistasis. The importance of epigenetics in development and disease susceptibility, as with structural variation, is becoming more apparent. Epigenetics provides the perfect regulatory mechanism for dynamic changes in global gene expression required for multiple cellular processes such as senescence. Tying it all together: epigenetics, genetics, cell cycle, and cancer. The role epigenetics has to play in cellular processes such as senescence, tumourigenesis and stem cell phenotypes has only recently been uncovered in any great detail. Holliday, in the first article after the introduction, still holds to the view that methylation is the key to epigenetics. Cancer epigenetics comes of age. It is important in epigenetics, because the hydroxymethyl group on the cytosine can possibly switch a gene on and off.
