Cell Cycle, Cancer, and Stem Cells

Cells go through additional growth.

• G1

• S

• G2

• M phase

Cells replicate DNA.

• G1

• S

• G2

• M phase

Some scientists name the stage where cells carry out their normal functions but are unlikely to divide. The name they give this stage is _________.

• G0

• G1

• G2

• G3

is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues and "decides" whether or not to move forward with division.

• checkpoint

• chromosome

• interphase

• tumor

Which one is not a checkpoint?

• G0 checkpoint

• G1 checkpoint

• G2 checkpoint

• Spindle checkpoint

Checks for cell size, nutrients, growth factors, and DNA damage.

• G1 checkpoint

• G2 checkpoint

• Spindle checkpoint

• DNA polymerase

Checks for DNA damage and DNA replication completeness.

• G1 checkpoint

• G2 checkpoint

• Spindle checkpoint

• DNA polymerase

What does NOT happen during interphase?

• growth

• DNA replication 

• obtaining nutrients

• cell divison

This process is the programmed death of a cell

• stem cell

• regulation

• apoptosis

• cytocide

Cancer creates abnormal cells by disrupting

• the cell cycle

• red blood cell formation

• DNA replication

• ATP synthesis
