Cancer Review

The diagram below represents the cell cycle.

When cells leave the cell cycle, they exit during G1 phase and then enter G0 phase, a resting period.  Most normal cells can leave G0 phase and reenter the cell cycle at G1 phase before entering S phase.  Cancer cells are different because they cannot enter G0 phase and are likely to do which of the following?

When carcinogens cause a failure in the regulation cell growth and development, what condition might occur?

Some genes code for the proteins that regulate cell growth and division.  A mutation in which of the following genes would lead to uncontrolled, abnormal cell division?

Cancer is often characterized by tumors.  Which would most likely trigger the formation of a tumor?

Cancer cells are body cells that do not function properly, leading to abnormal growth.  Which process does not function normally in cancer cells?

Scientists trying to find a cure for cancer are especially interested in studying which of the following topics?

Select ALL of the following that are carcinogens. (3 choices)
