Figure 28.11 depicts the eukaryotic cell cycle. Many cell types â€œexitâ€� the cell cycle and donâ€™t divide for prolonged periods, a state termedG0; some, for example neurons, never divide again. a. In what stage of the cell cycle do you suppose a cell might be when it exits the cell cycle and enters G0? b. The cell cycle is controlled by checkpoints, cyclins, and CDKs. Describe how biochemical events involving cyclins and CDKs might control passage of a dividing cell through the cell cycle.
