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 ...

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

A new study has punctured a longstanding assumption about the source of the most common type of DNA mutation seen in the genome--one that contributes to many genetic diseases, including cancer. A ...

Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide ...
