Scientists unravel key steps in the road to DNA repair

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 dangling single-strand end into intact ...

Human stem cell defenses activated by irradiation, study finds

Researchers from several Russian institutes, including MIPT, have found out how prolonged exposure to ionizing radiation affects human stem cells. They discovered that it causes a cell cycle delay, which leads to faster repairs ...

When editing bacteria with CRISPR, less is more

Systematically attenuating DNA targeting activity can achieve CRISPR-driven editing in bacteria, greatly boosting colony counts and even increasing the frequency of precise genome editing. This was shown in a study of the ...

Forks colliding: How DNA breaks during re-replication

Leveraging a novel system designed to examine the double-strand DNA breaks that occur as a consequence of gene amplification during DNA replication, Whitehead Institute scientists are bringing new clarity to the causes of ...
