Questions and Answers

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?

  • 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)
  • Which proteins may act to sensitize cells to apoptosis, in addition to functioning in proliferative pathways?

  • p53 and RB
  • c-Myc and several cyclin-dependent kinases (Cdks) (correct)
  • Only tumor suppressor genes
  • None of the above
