In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

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 ...

New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...
