Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

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

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 ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

An international research team has recovered ancient human mitochondrial and nuclear DNA directly from cave wall materials in ...
