What happens to the DNA during Mitosis
Why is the S (synthesis) phase important to the cell cycle
Why do there need to be checkpoints in the cell cycle?
Choose a description from the column on the right that matches the stage of the cell cycle it represents:

| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
S phase | arrow_right_alt | Cell division |
G2 phase | arrow_right_alt | Cell increases in size and prepares its DNA to replicate |
Mitosis (M) phase | arrow_right_alt | Resting, non-dividing cell |
G1 phase | arrow_right_alt | Replication of DNA |
G0 phase | arrow_right_alt | Continued cell growth getting ready for division |
Pick the correct answer for the question given:
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
The term where tumors attract blood vessels to itself to help supply nutrients and remove waste | arrow_right_alt | apoptosis |
The term for "programmed cell death" | arrow_right_alt | cancer |
Cancer cells arise from | arrow_right_alt | angiogenesis |
When a healthy cell stops dividing when close to another cell | arrow_right_alt | mutations in DNA |
A factor in the environment that can alter DNA sequence and cause cancer | arrow_right_alt | surgery |
The best initial type of cancer therapy for a tumor mass is usually | arrow_right_alt | contact inhibition |
This can result from uncontrolled cell growth | arrow_right_alt | carcinogen |
Match each item to the correct phase




Chromosomes become visible and nucleus begins to dissolve.
Chromosomes are split and moved to opposite sides of the cell.
The cell begins to split, and two new nuclei begin to form.
Chromosomes attach to spindle fibers and align along the center of the cell.
