Processes that regulate cell division in mammals include all ofthe following except:
| | rapid production of CDK enzymesthat activate cyclin proteins |
| | different cyclins and CDKs act atdifferent stages of the cell cycle to promote cell division. |
| | rapid degradation of cyclins afterCDK activation |
| | activated cyclin-CDK complexestrigger cell cycle events. |
| | rapid production of cyclin proteinsthat activate CDK enzymes. |
Defects in cell signaling can lead to a cancerous cell due toall of the following except:
| | overproduction of signals thattrigger cell division |
| | a defective signal-transductionprotein that stays in the inactivated state and fails to triggercell division. |
| | inactivation of proteins thatpromote apoptosis. |
| | a defective receptor that stays inthe activated state and triggers cell division continuously. |
| | overproduction of a receptor thattriggers cell division. |
