How cells select DNA damage repair pathways

DNA is well known as the blueprint of life, necessary for an organism to facilitate living processes. DNA can be damaged by various factors such as radical metabolites, radiation, and some toxic chemicals. As DNA is a molecule ...

Researchers reveal DNA repair mechanism

A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA.

How a single enzyme unleashes a complex DNA repair process

Our DNA is constantly exposed to damaging factors that can lead to aging and age-related diseases such as cancer. PARP1 is an important enzyme that facilitates the response to DNA damage by attaching chemical groups called ...

Male beetles neglect their genomes when competing for females

Male beetles face a trade-off between competing with other males for mating opportunities and repairing damage to their sperm DNA, according to a study published April 4 in the open access journal PLOS Biology by Mareike ...

Understanding why BRCA2 is linked to cancer risk

A new study shows exactly how the gene BRCA2, linked to susceptibility to breast and ovarian cancer, functions to repair damaged DNA. By studying BRCA2 at the level of single molecules, researchers at the University of California, ...

Researchers uncover the first steps driving antibiotic resistance

Antibiotic resistance is a global health threat. In 2019 alone, an estimated 1.3 million deaths were attributed to antibiotic resistant bacterial infections worldwide. Looking to contribute a solution to this growing problem, ...
