At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...

Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...

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 ...

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 ...

Cell division, a process fundamental to life, still holds surprises. Researchers from the University of Zurich and the ...
