Biology EpigenesisEpigenetics

Epigenetics is a term in biology used today to refer to features such as chromatin and DNA modifications that are stable over rounds of cell division but do not involve changes in the underlying DNA sequence of the organism.

 


Epigenetics
Epigenetics refers to modifications in gene expression that are controlled by heritable but potentially reversible changes in DNA methylation and/or chromatin structure.

Epigenetics
The term epigenetics has over time been used in various senses, in part because the Greek prefix epi- has at least six meanings in English (including 'on', 'after' and 'in addition'), ...

Epigenetic
The inheritance of a particular trait that is not encoded in the nucleotide sequence.

Epigenetic any factor which influences the phenotype which is not part of the genotype.

Epigenetics: The study of heritable changes in gene expression that occur without a change in DNA sequence. Epigenetic phenomena such as imprinting and paramutation violate Mendelian principles of heredity.

Epigenetic
Relating to, or produced by the chain of developmental processes in epigenesis that lead from genotype to phenotype after the initial action of the genes.
