In this phase of the cell cycle, the cell grows bigger.

• G1

• S

• G2

• mitosis/cytokinesis

In this phase of the cell cycle, the cell DNA is copied.

• S

• G2

• mitosis/cytokinesis

In general, the purpose of a checkpoint in the cell cycle is:

• To allow the cell to rest

• To check for any errors

• To signal cell replication

• To signal DNA replication

What phase of the cell cycle is most affected by cancer treatments like chemotherapy?

• G1 phase

• S phase

• G2 phase

• M phase
