What does a cell look like? If you had to draw one, you'd probably do the usual thing: a sort of fried egg with a nucleus yolk and a couple ribosomes peppered around, maybe a rough endoplasmic ...

When the researchers inhibited Plk1 in living cells, the cells remained in the prophase of mitosis for up to 10 hours—this normally only takes about 15 minutes.

How Cells Divide. By Rick Groleau; Posted 10.09.01; NOVA; Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes.

Cyclin B1–Cdk1 is the key initiator of mitosis, but when and where activation occurs has not been precisely determined in mammalian cells. Activation may occur in the nucleus or cytoplasm, as ...

In vertebrate cells, the nuclear entry of Cdc2–cyclin B1 (MPF 1,2,3) during prophase 4,5,6 is thought to be essential for the induction and coordination of M-phase events 7,8,9,10,11,12 ...
