Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

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 ...

DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Two teams of researchers have uncovered microscopic details of how a protein called photolyase uses light to repair DNA. The discovery could help develop sustainable technologies for chemical ...

A new study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most ...

In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...

Alcohol can harm more than your liver and heart—new insights reveal it damages DNA, increasing cancer risk. Experts explain ...
