DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Researchers have identified gene-regulatory variants that might have contributed to Neanderthals’ beefy jaws — offering a window on how the human face developed 1. This ‘non-coding’ sequence controls ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes ...

Neanderthals and humans mated millennia ago, and their legacy lives on in us today. Here's how. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA – its genome – and segregate it equally ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), ...

An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated over and over, become longer and more unstable as we age. The study found ...
