Textbook Question
Chapter 12, Problem 15QP
Which of the following mutations will result in cancer?
- a. homozygous recessive mutation in a tumor-suppressor gene coding for a nonfunctional protein
- b. dominant mutation in a tumor-suppressor gene in which the normal protein product is overexpressed
- c. homozygous recessive mutation in which there is a deletion in the coding region of a proto-oncogene, leaving it nonfunctional
- d. dominant mutation in a proto-oncogene in which the normal protein product is overexpressed

Distinguish between proto-oncogenes and tumor-suppressor genes. To become cancer promoting, do proto-oncogenes and tumor-suppressor genes undergo gain-of-function or loss-of-function mutations? Classify the following genes as proto-oncogenes or tumor-suppressor genes: p53, ras, BCL-2, JUN, MDM2, and p16.
Classify the following genes as proto-oncogenes or tumor-suppressor genes: p53, ras, Bcl-2, telomerase, jun, and
The p53 gene is a tumor-suppressor gene while Ras is a proto-oncogene. Mutation in either one can result in the transformation of a normal cell into a cancer cell. Explain the difference between the functions of the two proteins and how their mutation can lead to cancer development.
