WebMar 9, 2024 · In the cell cycle, there are three check points that involves cyclin-dependent kinases (cdks). Each cdk has its own specific cyclin that initiates either G1 phase, S phase, or M phase of cell cycle. Other check points that do not involve cdks also occurs at transition phases of cell cycles. Checkpoints in cell cycle is very important because it ... WebTo prevent a compromised cell from continuing to divide, there are internal control mechanisms that operate at three main cell cycle checkpoints at which the cell cycle can be stopped until conditions are favorable (Figure 1).
