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 ...

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

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

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 ...
