Why is cell division important for organisms (select all that apply)?
To repair damaged cells
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
