The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

Researchers have discovered a mechanism in DNA that regulates how disease-causing mutations are inherited. The team identified two enzymes that regulate a chemical modification, 6mA, in mitochondrial ...

New Houston Methodist research has revealed that a protein associated with neurodegenerative diseases such as dementia and ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and the ...

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 ...
