G1, S, G2.
300
Which phase of mitosis is this?
Anaphase
300

400
During cytokinesis, what is dividing?
The cytoplasm
400
Name one factor that can cause mutations leading to cancer.

400
DNA and RNA are examples of this type of macromolecule.
Nucleic Acids
400
During diffusion, particles move from an area of ________ concentration to an area of ______ concentration
High, Low
500
What could happen if checkpoints in the cell cycle fail?
Uncontrolled cell division (cancer).
500
Why do daughter cells produced by mitosis have identical DNA?
Because DNA is copied exactly before division.
500
Why are cancer cells dangerous to the body?
They crowd out normal cells and disrupt organ function.
500
