WebIncreases in the concentration of cyclin proteins are triggered by both external and internal signals. After the cell moves to the next stage of the cell cycle, the cyclins that were active in the previous stage are degraded. Figure 10.12 The concentrations of cyclin proteins change throughout the cell cycle. WebMPF provides a good example of how cyclins and Cdks can work together to drive a cell cycle transition.
