Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

Epigenetics is a rapidly growing field of study that focuses on the heritable changes in gene expression that occur without alterations to the underlying DNA sequence. These changes are caused by ...

The expression of genes has to be carefully regulated in cells; active genes give cells their identity and ability to function. Epigenetic features are just one way that cells control gene expression, ...

A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division.

Changes in histone modifications of genes involved in flowering. (a) The removal of Polycomb complexes by SDG7 protein. (b) Transcription elongation and the deposition of H3K36me3 by SDG8 protein. PRE ...

Northwestern Medicine scientists have discovered how molecular "traffic controllers" in cells influence aging and cellular ...

The genome is a fascinating place, consisting of complex loops of DNA that are transcribed into RNA, which is translated into protein. However, DNA expression is controlled by factors beyond the ...

Salk Institute researchers find new mode of epigenetic targeting, showing for the first time that genetic sequences can direct new DNA methylation patterns in plants LA JOLLA (November 21, 2025)—All ...
