DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among ...

Pictures of DNA often look very tidy—the strands of the double helix neatly wind around each other, making it seem like studying genetics should be relatively straightforward. In truth, these strands ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...
