New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

A protein long studied for its role in amyotrophic lateral sclerosis and frontotemporal dementia now appears to serve a second, equally critical function, safeguarding the integrity of human DNA.
