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 ...

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 ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...
