Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic letters before it divides.

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

A research team led by Professor ZHAO Guoping at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a crucial mechanism that helps regulate DNA damage repair, ...

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 ...

Objectives Understanding the molecular changes in the preclinical synovium is crucial for identifying factors that drive ...
