New findings are calling into question a long-held theory for how a dividing cell decides to stop the process of mitosis and restart the cell cycle. Chromosomes (blue) and mitoticspindle (green) ...

Chromosome Duplication Occurs Prior To Both Mitosis And Meiosis.

The G2 checkpoint ensures that DNA replication is complete and that any DNA damage that occurred during S phase has been ...

During cell division, adherent animal cells round up to create the precise spatial geometry required for accurate chromosome ...

Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...

Viruses insert “transposable elements” into the genetic material of host cells to replicate. While cells’ defense mechanisms have learned to silence most of these viral insertions, a few “jumping ...

How do we grow from a single fertilized egg into a fully grown person with trillions of cells? Our cells divide, of course! And it's no mean feat. Each time a cell divides, it must duplicate our 23 ...

Why do we need to understand the dynamics of the cell cycle? The cell cycle is a mechanism that controls and integrates the stages of DNA synthesis, mitosis, and cell division. This mechanism dictates ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...
