Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help ...

Biased gene conversion (BGC) is a neutral molecular process associated with meiotic recombination that preferentially favours the transmission of guanine (G) and cytosine (C) alleles over adenine (A) ...

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 ...

Cells are constantly subjected to DNA damage from a range of internal and environmental sources. It is estimated that cells can experience as many as 100,000 DNA lesions per day. One of the most ...

When it comes to cancer, tumor suppressor genes are usually thought of as the "good guys." These genes make proteins that protect and repair DNA in cells. If they stop functioning or there's not ...

You may have seen it in the news recently: a baby in Pennsylvania with a rare genetic disorder was healed with a personalized treatment that repaired his specific genetic mutation. The treatment was ...
