Cell Cycle

What role do checkpoints play in the cell cycle?

• They ensure that the cell is ready to proceed to the next phase.

• They promote cell division regardless of conditions.

• They prevent cells from entering the interphase stage.

• They allow cells to skip phases in the cycle.

What are the main phases of the cell cycle?

• Interphase (G1, S, G2) and M phase.

• Prophase, Metaphase, Anaphase, and Telophase.

• G1, G2, M, and Cytokinesis.

• S phase and G0 phase.

What is the difference between the cell cycle and cell division?

• The cell cycle includes all phases of growth and division, while cell division specifically refers to the M phase.

• Cell division is a part of the cell cycle that occurs only during the G1 phase.

• The cell cycle is only about cell growth, while cell division is about cell death.

• Cell division occurs in all phases of the cell cycle, including interphase.

What is cytokinesis?

• The process of DNA replication.

• The division of the cytoplasm, resulting in two separate cells.

• The synthesis of proteins in the ribosome.

• The formation of the nuclear envelope during cell division.

What is the significance of the S phase in the cell cycle?

• DNA repair occurs, ensuring genetic stability.

• DNA replication occurs, resulting in two copies of each chromosome.

• Cell growth and metabolism are enhanced during this phase.

• Chromosomes are separated into daughter cells.

What is mitosis?

• The process of cell division that results in two identical daughter cells.

• A type of cell division that produces four genetically different cells.

• The phase of the cell cycle where DNA is replicated.

• A process that occurs only in prokaryotic cells.

During what phase of the cell cycle does the cell grow?

• G1 phase.

• S phase.

• G2 phase.

• M phase.

How does the cell cycle relate to cancer?

• Uncontrolled cell division can lead to tumor formation and cancer.

• The cell cycle has no impact on cancer development.

• Cancer cells divide slower than normal cells.

• The cell cycle only affects healthy cells.

What occurs during the G2 phase of the cell cycle?

• The cell undergoes DNA replication.

• The cell continues to grow and prepares for mitosis.

• The cell divides into two daughter cells.

• The cell enters a resting state.

During what phase of the cell cycle does cell division occur?

• G1 phase

• S phase

• M phase

• G2 phase
