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 ...

DNA methylation plays an important role in separating us genetically from our closest relatives.

DNA methylation is an epigenetic modification in which a methyl group is added to a DNA base without changing the underlying DNA sequence. In mammals, the best-known form is 5-methylcytosine (5mC), ...

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 not ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

Mental disorders, such as obsessive-compulsive disorder (OCD) and bipolar disorder, can strongly affect daily life.

The visible effects of ageing on our body are in part linked to invisible changes in gene activity. The epigenetic process of DNA methylation — the addition or removal of tags called methyl groups — ...

DNA methylation is a highly studied epigenetic modification that is involved in regulating genome function and plays fundamental roles in development and disease. 1 It is linked to a broad range of ...
