Two teams of researchers have uncovered microscopic details of how a protein called photolyase uses light to repair DNA. The discovery could help develop sustainable technologies for chemical ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a ...

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 ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

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 ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
