Cell Cycle Quiz

What are the four main stages of the cell cycle?

• Interphase, Prophase, Metaphase, and Anaphase

• G1 phase, S phase, G2 phase, and M phase

• Phase 1, Phase 2, Phase 3, and Phase 4

• Growth, Division, Replication, and Maturation

Explain the process of interphase in the cell cycle.

• During interphase, the cell remains dormant and does not undergo any changes.

• Interphase is the phase where the cell divides into two daughter cells.

• Interphase is the phase where the cell carries out its specialized functions, such as producing hormones.

• During interphase, the cell grows, replicates its DNA, and prepares for cell division.

Describe the events that occur during the mitotic phase of the cell cycle.

• Division of the cytoplasm (cytokinesis) followed by nuclear division (mitosis)

• Nuclear division (meiosis) followed by division of the cytoplasm (cytokinesis)

• Nuclear division (mitosis) followed by division of the cytoplasm (cytokinesis)

• Cell growth followed by division of the cytoplasm (cytokinesis)

What is cytokinesis and when does it occur in the cell cycle?

• Cytokinesis occurs during the S phase of the cell cycle.

• Cytokinesis occurs after the completion of mitosis or meiosis.

• Cytokinesis occurs before the start of mitosis or meiosis.

• Cytokinesis occurs in the middle of mitosis or meiosis.

How is the cell cycle regulated in terms of growth factors and cyclins?

• Growth factors and cyclins control the cell cycle progression.

• Cell cycle is not regulated by growth factors and cyclins

• Cyclins have no effect on the cell cycle regulation

• Growth factors inhibit the cell cycle progression

Explain the role of cyclin-dependent kinases (CDKs) in the regulation of the cell cycle.

• CDKs regulate the cell cycle by controlling the progression from one phase to another.

• CDKs regulate the cell cycle by promoting uncontrolled cell division

• CDKs have no role in the regulation of the cell cycle

• CDKs only regulate the cell cycle in plant cells

What are the cell cycle checkpoints and why are they important?

• A way to stop the cell cycle completely

• A process to eliminate the cell cycle altogether

• A method to increase the speed of the cell cycle

• Control mechanisms to ensure proper progression of the cell cycle and maintain genomic integrity

Describe the specific events that occur at the G1 checkpoint.

• Cell enters the G2 phase

• Cell undergoes apoptosis

• Cell checks for DNA damage and ensures favorable environment for cell division

• Cell replicates its DNA

What happens at the G2 checkpoint and how is it regulated?

• The G2 checkpoint checks for RNA transcription and ensures cell division before entering mitosis.

• The G2 checkpoint checks for DNA damage and ensures DNA replication before entering mitosis.

• The G2 checkpoint checks for protein synthesis and ensures cell growth before entering mitosis.

• The G2 checkpoint checks for lipid production and ensures energy storage before entering mitosis.

Explain the significance of the M checkpoint in the cell cycle.

• The M checkpoint is responsible for protein synthesis in the cell cycle.

• The M checkpoint is involved in the formation of the cell membrane.

• The M checkpoint ensures proper alignment and attachment of chromosomes before cell division.

• The M checkpoint is where the cell prepares for DNA replication.
