Tokyo, Japan – 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 ...

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

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 ...

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 ...

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from ...

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 ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Cancer’s most catastrophic DNA damage has long looked like a crime scene without a culprit, with chromosomes shattered and ...

Using comparative molecular biology with human cGAS – which actually inhibits DNA repair – the scientists found that the naked mole-rat's enzyme has four key changes that facilitate the important work ...

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can play ...
