Cell Cycle Checkpoints and Cancer

What is the purpose the the cell cycle checkpoints?

• To repair damaged cells before they enter cell division.

• To remove damaged cells from an organism.

When is apoptosis initiated?

• When DNA damage is repaired.

• When cells are removed from the cell cycle.

• When DNA damage cannot be repaired.

This is the cell cycle checkpoint that makes sure environmental conditions are ideal for cell survival.

• G1 Checkpoint
• G2 Checkpoint
• M Checkpoint
• I Checkpoint

This is the cell cycle checkpoint that makes sure DNA has been replicated correctly during S phase.

• G1 Checkpoint
• G2 Checkpoint
• M Checkpoint
• I Checkpoint

This is the cell cycle checkpoint that makes sure the correct number of chromosomes are present and attached to microtubules.

• G1 Checkpoint
• G2 Checkpoint
• M Checkpoint
• I Checkpoint

The checkpoints that regulate the cell cycle can fail when ____ becomes damaged.

• DNA 
• Cell Membrane
• Mitochondria
• Ribosomes

Uncontrollable cell growth is known as _____

• Obesity
• Cancer
• Diabetes
• Hepatitis

Name the 3 checkpoints of the cell cycle

• Anaphase checkpoint, mitosis/metaphase checkpoint, and telophase checkpoint

• Interphase checkpoint, S phase checkpoint, and M phase checkpoint

• G1 checkpoint, G2 checkpoint, and S phase checkpoint

• G1 checkpoint, G2 checkpoint, and mitosis/metaphase checkpoint

What is the purpose of cell cycle checkpoints?

• To verify the processes at each stage have been completed correctly.

• To break up/slow down the cell cycle.

What is the correct process for the cell cycle?

• Cytokinesis, Mitosis then Interphase.

• Interphase, Mitosis then Cytokinesis.

• Interphase, Cytokinesis then Mitosis.

• Mitosis, Interphase then Cytokinesis.
