• uncontrolled cell growth

• cells that have lost the ability to reproduce

• cells which grow abnormally and no longer function correctly

• cells which create abnormal tissue

Which of the following is NOT a characteristic of cancer?

• Avoids apoptosis

• Rapid cell growth

• Promotes angiogenesis

• Repairs DNA damage before dividing

A proto-oncogene that has mutated is

• called an oncogene

• analagous to having your foot stuck on the gas pedal

• one step toward the development of cancer

• all of theses options are true of mutated proto-oncogenes

Mutations that occur in an individual during their lifetime and are only passed on to the cells that result from cell division of the mutated cell are called _____ mutations.

When the cell cycle functions properly, the result is

• 2 genetically identical daughter cells

• 2 genetically different daughter cells

• 4 daughter cells with 1/2 the DNA of the parent cell

• 4 daughter cells that resemble the parent cell

Substances that are known to cause cancer are called

• inducers

• carcinogens

• pathogens

• supressors

All of the following are known risk factors for developing cancer EXCEPT:

• Obesity

• Age (older)

• BRCA-1 genes

• Exercise

A mutation occurs in a gene for a receptor protein on a cell responsible for binding to growth factors. The mutation activates the receptor, even if growth factors are not present. This mutation most likely results in:

• increase in cell division

• decrease in cell division

• abnormally large cells

• all of these are likely to result from the mutation
