DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.
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 ...
A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...
It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...
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 ...
The cancer drugs called PARP inhibitors have a puzzling reputation: even though they are treatment mainstays for multiple forms of cancer, they can damage cancer-killing T cells and disrupt the ...
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, ...
