Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects ...
