A protein tied to ALS and dementia may have a much bigger role in disease than scientists realized. Researchers found that ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

Researchers have uncovered how a key DNA repair enzyme is recruited and activated inside cells, answering long-standing questions about how cells protect and repair their DNA and providing the ...
