Every cell in the body has the same DNA, but different cell types—such as muscle or brain cells—use different parts of it.

Michael Buck, PhD, professor of biochemistry in the Jacobs School, recently received NIH funding to explore how molecular readers of DNA access and activate seemingly hidden genes.

Aging, neurological diseases and our bodies’ stress response are all linked to the tiny power plants inside each cell known as mitochondria. To function properly, mitochondria must first read ...

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 — ...

Scientists have found that twisting structures in DNA long mistaken for knots are actually something else entirely. Inside cells, DNA gets twisted, copied, and pulled apart. The twists can influence ...

Researchers at the University of Exeter have created a detailed temporal map of chemical changes to DNA through development and aging of the human brain, offering new insights into how conditions such ...

Researchers including those at the University of Tokyo have made a surprising discovery hiding in people's mouths: Inocles, giant DNA elements that had previously escaped detection. These appear to ...
