Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

The precise temporal control of DNA replication and the coordinated activation of repair pathways are fundamental to genome stability. Eukaryotic chromosomes replicate in a defined programme during S ...

DNA replication is a vital process in all biological systems. To faithfully duplicate the entire genome, DNA replication adheres to a strict temporal and spatial program 1. Even under physiological ...

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 ...

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 ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...

His decoding of the blueprint for life with Francis H.C. Crick made him one of the most important scientists of the 20th century. He wrote a celebrated memoir and later ignited an uproar with racist ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to ...
