A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic ...

While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

An analysis of genetic data from over 900,000 people shows that certain stretches of DNA, made up of short sequences repeated ...

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 ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...

RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act ...
