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 ...
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 ...
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 ...
In a quiet lab at Utrecht University, researchers have built a tool that lets you watch one of life’s most serious crises unfold in real time. Inside every cell, DNA breaks, repairs, and sometimes ...
DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...
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 ...
