Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

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 ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
