It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Physical pressure can stop cancer cells from growing large enough to divide, revealing why squeezed tumors may stall.

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Researchers have revealed a surprising new role for a key protein in cell division. The discovery, reported in two back-to-back papers, challenges long-standing models and textbook accounts in biology ...

A simulated cell in the early stages of division. Left half shows cytoplasm (blue cubes), mRNA degradation machinery molecules (pink), and sugar transporters (brown). Right half adds the membrane ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
