• To reproduce

• To grow

• To initiate apoptosis in damaged cells

Why does cell division remain important to an adult organism even after it is fully developed?

• To repair damaged cells

• To differentiate cells

• To initiate apoptosis

• To stimulate growth

Cells divide, differentiate, or die. What is differentiation?

• The process of programmed cell death

• The process of cell division

• The process in which a cell specializes in structure and function

• The process of DNA replication

What is apoptosis? What is its purpose?

• Programmed cell death to eliminate unnecessary cells

• The process of cell division

• The process in which a cell specializes in structure and function

• The process of DNA replication

What happens if cell cycle regulators don't function properly?

• The organism may end up with too few or too many cells

• The cell cycle will be halted completely

• The cell will undergo apoptosis

• The cell will differentiate into a specialized cell

Cells go through periods of growth and division. Cell division occurs during

• G1 phase

• S phase

• G2 phase

• M phase

In general, what is the purpose of a checkpoint in the cell cycle?

• To ensure the cell is ready to go into the next phase of the cell cycle

• To initiate apoptosis in damaged cells

• To stimulate cell growth

• To differentiate cells

What is the G0 phase of the cell cycle?

• The phase where the cell grows and replicates its DNA

• The phase where the cell divides

• The phase where the cell rests

• The phase where the cell undergoes apoptosis

In some types of colon cancer, stem cells have a mutation in the APC gene. What happens if the APC gene is mutated?

• A tumor can form

• Cell division is halted

• Apoptosis is initiated

• Cell differentiation is stimulated

Normally, proto-oncogenes stimulate the cell cycle. What are oncogenes and how do they affect the cell cycle?

• Oncogenes are mutated proto-oncogenes that inhibit the cell cycle

• Oncogenes are normal genes that stimulate apoptosis

• Oncogenes are mutated tumor suppressor genes that stimulate cell differentiation

• Oncogenes are mutated proto-oncogenes that increase stimulation of the cell cycle
