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 ...

In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations in mitochondrial DNA using a genetic tool known as a base editor. The ...

New study shows that in women with BRCA1 or BRCA2 mutations, their breast cells already carry a clear pattern of DNA “damage ...

From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...

Yuan He aims to understand how cells read and repair their genomes. His research encompasses two primary areas: transcription, in which genetic information is copied from DNA into messenger RNA, and ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

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