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, ...

DNA can be damaged by normal cellular processes as well as external factors such as UV radiation and chemicals. Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Researchers have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. Researchers from the University of Birmingham have uncovered ...

Each cell in our body experiences up to tens of thousands of DNA-damaging events per day, primarily from routine cellular maintenance or exposure to toxins in our environment. Despite the high ...

Macquarie University researchers have discovered a naturally occurring protein found in human cells plays a powerful role in repairing damaged DNA—the molecule that carries the genetic instructions ...

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 ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...

Francesca Storici consults at Tessera Therapeutics. She has received funding from the National Institutes of Health and the National Science Foundation. Your DNA is continually damaged by sources both ...

New research from the Kind Group at the Hubrecht Institute sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human ...
