Based on the descriptions provided, which disorder most directly relates to malfunctions in the cell cycle?
Melanoma
200
During mitosis, cells divide over _____ different phases.
4 or 5 (if you include cytokinesis)
200
Cancerous cells that continue to build on each other form a ____________.
Tumor
200
Which treatment uses surgery to remove cancerous cells from the body?
Resection
400
Which phase is the shortest part of the cell cycle?
M phase (mitosis)
400
What is the correct order of the stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase (PMAT)
You can include cytokinesis
400
______ percent of cancer diagnoses have no known cause.
40
400
What cancer treatment uses high beams of energy to damage the DNA in a cancer cell?
Radiation
600
What happens during the S phase of the cell cycle?
DNA replicates in the nucleus.
600
The phase of mitosis where original cell splits into two identical cells is called ______________________.
Cytokinesis
600
Both of these cells have DNA damage. Why does only one of them become cancerous?
One of them undergoes apoptosis (cell death) and the other one does not.
600
Which treatment uses chemicals to kill cancerous cells and/or stop them from dividing.
Chemotherapy
800
What happens during interphase?
The cell prepares for division
800
What 3 processes are made possible by cell division?
Growth, maintenance, repair
800
What are two ways (routes) that cancer metastasizes in the body?
Through the blood vessels and lymph nodes.
800
What are the 3 types of imaging scans we talked about in class?
**This won't be on the test**
CT scan, MRI, X-Ray
1000
What two events happen during the G2 phase of the cell cycle?
The cell makes proteins and organelles
The cell prepares for mitosis
1000
Which stage of mitosis shows the chromatids lining up in the middle of the cell?
Metaphase
1000
What are tumor suppressor genes, and how do they contribute to cancer?
Tumor suppressor genes are responsible for apoptosis (programmed cell death), when the gene is damaged the cell doesn't die and continues to replicate.

What is angiogenesis? How does it affect cancer?
Angiogenesis is the creation of blood vessels in the body. By preventing angiogenesis, we can cut off the blood supply to the tumor and hopefully keep it from growing.
