1. Epigenetics
   Epigenetics: 1. The study of heritable changes in gene function that occur without a change in the sequence of the DNA. For example: The process of DNA methylation; and The process of chromatin remodeling. 2. The study of certain processes that occur in embryonic development. For example: X inactiva...

2. epigenetics
   The study of mechanisms involved in the production of phenotypic complexity in morphogenesis. According to the epigenetic view of differentiation, the cell makes a series of choices (some of which may have no obvious phenotypic expression, and are spoken of as determination events) that lead to the eventual differentiated state. Thus, selective gene repression or derepression at an early stage in differentiation will have a wide-ranging consequence in restricting the possible fate of the cell.

5. epigenetics
   (from the article `Life Sciences`) The genome is often called the blueprint of life, but it is the epigenome—the way the genome is modified chemically and packaged—that defines how the ...

6. Epigenetics
   In biology, and specifically genetics, `epigenetics` is the study of changes produced in gene expression caused by mechanisms other than changes in the underlying DNA sequence – hence the name epi- (Greek: επί- over, above, outer) -genetics. Examples of such cha...
