Cell Cycle AP Biology

During which stage of interphase does the DNA duplicate.

• M Phase

• G1 Phase

• S Phase

• G2 Phase

In the G1 stage of the cell cycle, the cell

• Grows

• Matures

• Carries on normal activities

• All of the above

How does the concentration of cyclin change as a cell goes through the cell cycle?

• Cyclin concentration remains constant.

• Cyclin concentration increases during interphase and decreases during mitosis.

• Cyclin concentration decreases during interphase and increases during mitosis.

• Cyclin concentration is inversely related to MPF concentrations.

How does the concentration of cyclin dependent kinases (Cdk) change as the cell proceeds through the cell cycle?

• Cdk concentration remains constant.

• Cdk concentration increases during interphase and decreases during mitosis.

• Cdk concentration decreases during interphase and increases during mitosis.

• Cdk concentration correlates directly with MPF concentration.

is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues and "decides" whether or not to move forward with division.

• checkpoint

• chromosome

• interphase

• tumor

• 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

• 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

• enzymes

• insulin

• hemoglobin

• 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 the ​ (a)   stage of ​ (b)   , the combination signals DNA replication

• G2

• S

• prophase

• metaphase

• anaphase

• telophase

• mitosis

• cytokinesis

• interphase

• G1
