1. The diagrams (A and B) below represent the two common types of cancer genes; one diagram illustrates mutation/s in a typical tumor suppressor gene and the other illustrates mutation/s that change a proto-oncogene to an oncogene. No mutant alleles One mutant allele No mutant alleles One mutant allele Two mutant alleles Mutation Mutation Mutation A Normal cell division Excessive cell proliferation B Normal cell division Normal cell division Excessive cell proliferation 1a. Identify which type (tumor suppressor or proto-oncogene to an oncogene) is illustrated by each diagram (A and B) and describe the differences. 1b. Discuss which of the two illustrations above show a cancer gene with allele/s that acts recessively, and which shows a gene with allele/s that act in a dominant fashion.

are changes to the order of nucleotides in a segment of DNA that codes for a protein. Proto-oncogenes Tumor suppressor genes Gene mutations Negative regulators
Which of the following is not a characteristic of cancer cells? a. less cytoplasmic volume than normal cells b. an absence of cyclin c. loss of adhesion to other cells d. loss of control of cell division e. loss of normal control of G1/S phase transition
Figure 10.13 Rb and other proteins that negatively regulate the cell cycle are sometimes called tumor suppressors. Why do you think the name tumor suppressor might be appropriate for these proteins?
With regard to cancer cells, which of the following statementsare true?A. Cancer cells are clonal, which means they are derived from asingle mutant cell.B. To become cancerous, cells usually accumulate multiplegenetic changes that eventually result in uncontrolledgrowth.C. Most cancers are caused by oncogenic viruses.D. Cancer cells have lost the ability to properly regulate celldivision.
Most forms of cancer involvea. the activation of a single oncogene.b. the inactivation of a single tumor-suppressor gene.c. the activation of multiple oncogenes.d. the activation of multiple oncogenes and the inactivation ofmultiple tumor-suppressor genes.
Which of the following is true of tumor suppressor genes? Group of answer choices a) If this gene is overactive, it becomes an oncogene b) If one of the alleles is mutated, there is usually little effect. Two inactivating mutations are usually required for loss of function (recessive mutation). c) If one copy is lost, the gene no longer functions (dominant mutation) d) Tumor suppressors genes usually cause mitosis or cell growth e) Tumor suppressor genes decrease apoptosis
1. a)Proteins that stimulate/promote progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. b)Proteins that inhibit progression through the cell cycle are encoded by (oncogenes or tumor suppressor genes). Boldface one. c)What is the difference between a proto-oncogene and an oncogene? d)To cause cancer, proto-oncogenes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one. e)To cause cancer, tumor suppressor genes require (1 or 2)allele(s) to be mutated and therefore are considered (dominant or recessive). The mutation results in a (loss or gain) of function. For each underlined pair, boldface one.
