Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

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 ...

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 ...

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, ...

Using comparative molecular biology with human cGAS – which actually inhibits DNA repair – the scientists found that the naked mole-rat's enzyme has four key changes that facilitate the important work ...

The bowhead whale’s remarkable lifespan and low cancer risk stem from a finely tuned DNA repair system driven by a unique protein, CIRBP. Scientists found that this mechanism not only preserves the ...
