Epigenetics, the dynamic regulation of genetic expression, involves complex molecular mechanisms. While the process of gene silencing by methylating the H3K27 position in histones is understood, not ...

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 plays a critical role in human health by regulating gene expression without the direct modification of DNA sequence. Aberrant epigenetic modifications mediated by changes in DNA and ...

Epigenetics is an emerging field of scientific research exploring the study of gene expression changes that occur without alterations to the DNA sequence itself. Image Credit: Juan ...

The central dogma proposed that genetic information predominantly transfers from DNA to RNA during gene expression to make a functional product protein. This absolute theory has been debunked because ...

Researchers assessed DNA methylation at 800,000 sites in the genome in blood samples collected from 900 people. The study includes extensive clinical information on participants, who all provided ...

Why do identical twins sometimes experience different health outcomes as they age? How is it that a pregnant woman’s nutrition can influence her unborn child’s future risk of developing certain ...

Ancestral toxins cause disease for 20 generations. Epigenetic health defects in kidney, testis, and ovary intensify over many centuries, impacting evolutionary biology.
