This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes.

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process.

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in ...

James Watson, a renowned molecular biologist and one of the Nobel Prize winners for discovering the structure of DNA, died Thursday after a brief illness, according to a statement from his former ...
