Programmed cell death is called

• apoptosis
• cytokinesis
• interphase
• cancer

The normal function of a tumor suppressor gene is 

• to produce growth signals
• to code for proteins that inhibit, or slow, cell division
• to cause the cell to move faster through the cell cycle
• to attack cancer cells in the body

How does the concentration of cyclin change as a cell goes through the cell cycle?

• Cyclin concentration remains constant.
• Cyclin concentration increases during interphase and decreases during mitosis.
• Cyclin concentration decreases during interphase and increases during mitosis.
• Cyclin concentration is inversely related to MPF concentrations.

How does the concentration of cyclin dependent kinases (Cdk) change as the cell proceeds through the cell cycle?

• Cdk concentration remains constant.
• Cdk concentration increases during interphase and decreases during mitosis.
• Cdk concentration decreases during interphase and increases during mitosis.
• Cdk concentration correlates directly with MPF concentration.
