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 ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

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 ...
