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 ...

University of Pittsburgh researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in ...

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 ...

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 ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without ...
