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 ...

DNA methylation plays a key role in physiological processes including regulating gene expression and is a widely used biomarker for age prediction and the identification of body fluids. Traditionally, ...

beds.ac.uk Background Epigenetics is the study of processes—beyond DNA sequence alteration—producing heritable characteristics. For example, DNA methylation modifies gene expression without altering ...
