What is the main purpose of regulating cell proliferation and death in multicellular organisms?
What is the main purpose of regulating cell proliferation and death in multicellular organisms?
- To prevent the accumulation of damaged cells (correct)
- To suppress the natural process of cell renewal
- To create a conducive environment for pathogens
- To enhance tissue growth without limits
What evidence supports the link between the cell cycle and apoptosis?
What evidence supports the link between the cell cycle and apoptosis?
- Tumor suppressor genes are not involved in regulating apoptosis
- There is no known connection between cell cycle progression and programmed cell death
- Manipulation of the cell cycle has no effect on the apoptotic response
- Accumulated evidence suggests that cell cycle manipulation can prevent or induce an apoptotic response (correct)
