- Figure 28.11 depicts the eukaryotic cell cycle. Many cell types “exitâ€� the cell cycle and don’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.of my celle chose are wels smaller than normal.

In Model 1, if the length of the arrow represents time, then for those cancerous cells, what hap pens to the time that is necessary for the cell cycle? What implication might this have for doctors who are treating cancer patients? Why? Living things must grow and develop. At times they suffer injuries or damage, or cells simply wear out.
