Researchers have figured out how the human body keeps essential genes switched "on" and silences the vast stretches of genetic repeats and "junk" DNA.
Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine. The research is the fi... Read Post
Cells control which genes they express by multiple mechanisms, one of which is the direct modification of DNA with small molecules. Methylation of genes effectively silences them, and excess DNA methylation, particularly of genes th... Read Post
