• Different cyclin/CDK combinations control different activities at different stages of the cell cycle:

  • In the ​ (a)   stage of ​ (b)   , the combination signals the start of the cell cycle (and the end of it)

• G1

• G2

• S

• prophase

• metaphase

• anaphase

• telophase

• interphase

• mitosis

• cytokinesis

• The timing and rate of cell division is controlled by a combination of two substances: 

• proteins called​ ​ (a)   bind to enzymes called ​ (b)   during interphase and mitosis

• cyclins

• cyclin-dependent kinases (CDKs)

• carcinogens

• centromeres

• spindle fibers

• aster fibers

• centrioles

• motor proteins

• microfilaments

• The cell cycle has built in checkpoints that monitor the cell cycle and can stop it if something goes wrong: 

  • near the end of the​ (a)   stage of ​interphase , a checkpoint monitors for DNA damage and can stop the cycle before entering the ​ (b)   stage of interphase

• G1

• S

• G2

• Different cyclin/CDK combinations control different activities at different stages of the cell cycle:

  • In ​ (a)   of ​ (b)   , the combination signals nuclear division to start

• prophase

• metaphase

• anaphase

• telophase

• mitosis

• cytokinesis
