Question

Which of the following statements about tumor suppressor genes is false? Gene amplification of a tumor suppressor gene is less dangerous than gene amplification of a proto-oncogene. Cells with one functional copy of a tumor suppressor gene will usually proliferate faster than normal cells. p53 is a tumor suppressor gene. Inactivation of tumor suppressor genes leads to enhanced cell survival and proliferation. A mutation in a tumor-suppressor gene that renders the tumor-suppressor protein to be constitutively active often leads to cancer.

Answer 1

Answer:

Cells with one functional copy of a tumor suppressor gene will usually proliferate faster than normal cells.

Explanation:

tumor suppressor commonly referred to as antioncogene gene can be define as protein  making gene that produces specific protein that helps control cell growth. usually a mutation gene of the tumor suppressor will bring about cancer that is a mutation which causes abnormality in the growth can alter the cell and bring about cancer. they are also called brakes as they help obstruct,brake and act as a suppressor of tumor/cancer.

Answer 2

Answer:

Cells with one functional copy of a tumor suppressor gene will usually proliferate faster than normal cells.

Explanation:

For tumor suppressor genes, the cancer-causing mutations generated are  recessive meaning that both copies/alleles of the normal gene must be removed or inactivated in the diploid somatic cell before an effect is seen i.e. they act in a recesnsive loss of function maner.
