Cell Cycle Phases and Functions

The video explores the cell cycle, focusing on interphase and M phase. Interphase is divided into G1, S, and G2 phases, each with specific functions like cell growth, DNA replication, and preparation for mitosis. The G0 phase is discussed as a resting stage with quiescent and senescent states. The video concludes with an introduction to the M phase, which includes mitosis and meiosis.

What are the two main phases of the cell cycle?

• G1 phase and S phase

• G0 phase and G2 phase

• Interphase and M phase

• Mitosis and Meiosis

Which phase of interphase is responsible for cell growth and organelle duplication?

• M phase

• S phase

• G1 phase

• G2 phase

During which phase does DNA replication occur?

• M phase

• S phase

• G1 phase

• G2 phase

What is the primary function of the G2 phase?

• Cell division

• DNA replication

• Organelle duplication

• Cell growth and preparation for mitosis

Which phase is known for its role in preparing the cell for division?

• G1 phase

• M phase

• G2 phase

• S phase

What is the main activity of the S phase?

• Cell division

• Protein synthesis

• DNA replication

• Cell growth

What is the G0 phase often referred to as?

• Synthesis phase

• Division phase

• Growth phase

• Resting phase

What happens to cells in the quiescent stage of the G0 phase?

• They remain metabolically active but do not divide

• They divide rapidly

• They undergo DNA replication

• They prepare for mitosis

What is the senescent phase in the G0 phase?

• A phase where cells can re-enter the cell cycle

• A phase where cells permanently stop dividing

• A phase of rapid cell division

• A phase of DNA synthesis

What are the two types of cell division that can occur during the M phase?

• G1 phase and G2 phase

• Mitosis and Meiosis

• S phase and G0 phase

• Interphase and Mitosis
