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

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

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 ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

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

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 ...

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 paper based on long-lost documents confirms that DNA discoverer Rosalind Franklin should be credited for discovering the double helix. When you purchase through links on our site, we may earn an ...
