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 ...

Researchers have modeled a key mechanism by which DNA replicates. The study could help identify new targets to treat disease. Knowing the structure of a complex biological system isn't nearly enough ...

A new study has found that the photosynthetic bacterium Synechococcus elongatus uses a circadian clock to precisely time DNA replication, and that interrupting this circadian rhythm prevents ...

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 ...
