Most methylation occurs at specific locations in the DNA, typically on a cytosine (C) that sits next to a guanine (G)—and is called CG methylation. More than 80 percent of all CG sequences in the ...

Not all genes are active at all times. DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression. This straightforward experiment demonstrated that it was ...

Researchers found that accelerated biological aging, measured via DNA methylation, predicts frailty, cognitive decline, and ...
