Gene Regulation and Cell Cycle

Time period between cell divisions.

• Anaphase
• Mitosis
• Cytokinesis
• Interphase

3 stages of interphase

• G1, M, G2
• M, C, S
• G1, S, G2
• P, M, G1

During which stage of interphase does the DNA duplicate.

• M Phase
• G1 Phase
• S Phase
• G2 Phase

Apoptosis is
