2. Cell Cycle Stages
The life of a cell is regulated by numerous checkpoints and proteins
A mutation in a protein that is meant to either SLOW or STOP the cell cycle can cause a cell to LOSE CONTROL

3. CANCER Is known as UNCONTROLLED cell division
It happens when REGULATION of the cell cycle has broken down
CANCER CELLS:
Divide more often than do healthy cells
May form disorganized clumps called TUMORS
Comes from normal cells that have suffered damage to the genes that help make proteins involved in Cell Cycle Regulation

4. Which disease most likely occurs after excessive exposure to ultraviolet radiation? A. malaria B. asthma C. skin cancer D. polio

5. Some cancers are caused by mutations that stop certain proteins from working. The inactivation of what kind of protein could lead to cancer?
A. one that sped up the cell cycle
B. one that slowed down the cell cycle
C. one that acted as a growth-promoting molecule
D. one that responded to growth-promoting molecules

6. Cancer is often characterized by tumors
Cancer is often characterized by tumors. Which would most likely trigger the formation of a tumor?
A. a parasite that both lived and reproduced within the human body B. a change in the DNA sequence of a gene that codes for skin coloration C. a bacterial infection that caused inflammation and swelling in body tissues D. a mutation in a gene that codes for a protein regulating cell
