Which of the Following Statements About Tumor Suppressor Genes Is

Question

Which of the following statements about tumor suppressor genes is FALSE?
A)Gene amplification of a tumor suppressor gene is less dangerous than gene amplification of a proto-oncogene.
B)Cells with one functional copy of a tumor suppressor gene will usually proliferate faster than normal cells.
C)Inactivation of tumor suppressor genes leads to enhanced cell survival and proliferation.
D)Individuals with only one functional copy of a tumor suppressor gene are more prone to cancer than individuals with two functional copies of a tumor suppressor gene.

Accepted Answer

Cells with one functional copy of a tumor suppressor gene will usually proliferate slower and have a higher risk of becoming cancerous than normal cells. Therefore, statement B is false. The other statements are true - gene amplification of a tumor suppressor gene is less dangerous than gene amplification of a proto-oncogene, inactivation of tumor suppressor genes leads to enhanced cell survival and proliferation, and individuals with only one functional copy of a tumor suppressor gene are more prone to cancer than individuals with two functional copies of a tumor suppressor gene.
