Most chemotherapy agents kill cancer cells by affecting the S-phase of the cell cycle. Based on the diagram above and your knowledge of the cell cycle, which of the following best explains why the S-phase is targeted by chemotherapy agents?

• Because the cell grows and is most active during the S-phase.

• Because the cell divides and creates new cells during the S-phase

• Because the cell duplicates its DNA for its daughter cells during the S-phase

• Because the S-phase lasts the longest amount of time of all the cell cycle phase.
