How is the cell cycle regulated?

MPF provides a good example of how cyclins and Cdks can work together to drive a cell cycle transition. Like a typical cyclin, M cyclin stays at low levels for much of the cell cycle, but builds up as the cell approaches the G 2 _2 2 start subscript, 2, end subscript /M transition. read more

In this section, we will review the biological regulators of the cell cycle. Control of the cell cycle is necessary for a couple of reasons. First, if the cell cycle were not regulated, cells could constantly undergo cell division. read more

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods. read more
