Epigenetics is the study of changes in gene expression caused by certain base pairs in DNA, or RNA, being `turned off` or `turned on` again, through chemical reactions. In biology, and specifically genetics, epigenetics is mostly the study of heritable changes that are not caused by changes in the DNA sequence; to a lesser extent, epigenetics ...

the study of chemical markers that are added to DNA and affect its three dimensional structure related to how tightly it is packaged to form chromosomes. This mechanism impacts whether or not a gene will be expressed.

(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 ...

According to the epigenetic view of differentiation, the cell makes a series of choices (some of which may have no obvious phonotypic expression and are spoken of as determination events) that lead to the eventual differentiated state. Th...

(ep″ĭ-jә-net´iks) the study of heritable changes in the function of genes that occur without changes in the DNA sequence, occurring during development and cell proliferation and including mechanisms such as DNA methylation.

The study of heritable changes to DNA in which the genetic sequence remains unchanged but small chemical groups are added to the DNA. The addition of these groups affects how a gene works.

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.

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 inactivation (the inactivation of one X chromosome in fema...
