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 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 ...
This Brush Up is sponsored by Cayman Chemical. Learn more about chemical inhibitors of histone modification. Histone modification affects how tightly DNA wraps around histone proteins, yielding ...
DNA and RNA epigenetics, once thought to be separate, have now been found to work together to fine-tune gene expression. When you purchase through links on our site, we may earn an affiliate ...

Environmental factors significantly impact gene expression through epigenetic modifications
Epigenetics, the study of changes in gene function that do not involve alterations to the DNA sequence, plays a pivotal role in understanding the complex interplay between genetics and the environment ...
Nutritional epigenetics examines how maternal diet influences fetal gene expression through mechanisms such as DNA methylation, thereby shaping lifelong risks of metabolic, neurodevelopmental, and ...
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 ...
