Cell Cycle Checkpoints

What is the purpose of cell cycle checkpoints?

• To verify the processes at each stage have been completed correctly.

• To break up/slow down the cell cycle.

How many main cell cycle checkpoints are there?

• 1

• 2

• 3

• 4

What is the correct order of the cell cycle checkpoints?

• G2/M, G1/S then spindle assembly.

• G2/M, spindle assembly then G1/S.

• G1/S, G2/M then spindle assembly.

• Spindle assembly, G2/M then G1/S.

Which checkpoint checks for DNA damage and sufficient resources?

• G1/S

• G2/M

• Spindle assembly

• 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

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.

• chromosome

• interphase
