How is the cell cycle controlled
WebCell cycle checkpoints operate as DNA surveillance mechanisms that prevent the accumulation and propagation of genetic errors during cell division. Checkpoints can delay cell cycle progression or, in response to irreparable DNA damage, induce cell … WebPrecise temporal control of these cyclin-CDK kinase activities is crucial in establishing transitions from one cell-cycle phase to the next and in ensuring that cell-cycle events are executed in the correct order. 3, 11 The cell-cycle regulation of cyclin D, E, A, and B1 levels plays a critical role in this process (Fig. 5-3).
