review questions
Review Questions
  • What are and what happens during the phases of the cell cycle?
  • Which proteins are involved in the regulation of the cell cycle?
  • Which cyclins and cyclin-dependent kinases are most important in individual phases of the cell cycle?
  • What are four mechanisms for regulating cyclin-dependent kinase activity?
  • What role do p53, p21, and pRb play in the G1 to S transition?
