Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Organisms like eukaryotes and prokaryotes have sophisticated mechanisms of DNA repair after damage. Failure of repairing the DNA damage is considered to be the cause of induction of cell death, ...

The evolutionary drive to maintain neurons that we see in jellyfish and sea anemones is perhaps one of the reasons why sleep is essential for humans today, Appelbaum said.

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 ...

A new UCLA Health study has discovered in mouse models that genes associated with repairing mismatched DNA are critical in eliciting damages to neurons that are most vulnerable in Huntington's disease ...

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 ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...
