MeSH Heading: Epigenesis, Genetic
Tree Number(s): G05.308.203
Unique ID: D044127
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D044127
Scope Note: A genetic process by which the adult organism is realized via mechanisms that lead to the restriction in the possible fates of cells, eventually leading to their differentiated state. Mechanisms involved cause heritable changes to cells without changes to DNA sequence such as DNA METHYLATION; HISTONE modification; DNA REPLICATION TIMING; NUCLEOSOME positioning; and heterochromatization which result in selective gene expression or repression.
Entry Term(s): Epigenetic Process; Epigenetic Processes; Epigenetics Processes
