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 ...
Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Those 'DNA knots' weren't knots at all, and the truth is stranger
For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...
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 ...
When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...
Labs around the world are trying to turn cells into autobiographers, tracking their own development from embryos to adults. By Carl Zimmer Shortly after conception, a fertilized egg divides, becoming ...
