Cell Cycle Review

Why would a cell need to divide?

• to repair damaged DNA

• to prevent cancer

• to carry out protein synthesis

• to replace a damaged cell

What is the correct order of the cell cycle?

• M, G1, S, G2

• G1, G2, S, M

• S, G1, G2, M

• G1, S, G2, M

In which stage of interphase is DNA replicated?

• S phase

• G1 phase

• G2 phase

• G0 phase

During which part of the cell cycle does the cell grow and prepare for division?

• Prophase

• Interphase

• Mitosis

• Cytokinesis

During which stage of the cell cycle does the cell make organelles specifically to help with cell division?

• S phase

• M phase - DNA repair

Programmed cell death, or cellular suicide, is referred to as

• Apoptosis
