- Which of the following statements about cancer is false? (a) oncogenes arise from mutations in proto-oncogenes (b) tumor suppressor genes normally interact with growth-inhibiting factors to block cell division (c) more than 120 cancer-driving genes have been discovered (d) oncogenes were first discovered in mouse models for cancer (e) the development of cancer is usually a multistep process involving both oncogenes and mutated tumor suppressor genesarrow_forwardWhich of the following accurately compares tumor suppressor genes and proto-oncogenes? A. Both tumor suppressor and proto-oncogenes prevent the spread of cancer by targeting and destroying existing cancer cells. B. A person who has both tumor suppressor and proto-oncogenes will always develop cancer. C. Proto-oncogenes code for growth factors, while tumor suppressor genes inhibit cell division of damaged cells. D. When a proto-oncogene mutates, it becomes a tumor suppressor gene.arrow_forwardFor cancer to occur in an individual which of the following must occur? a an accumulation of multiple mutations in many different cells b a deletion of part of a gene c an accumulation of multiple mutations in an individual cell d chromosomal segment deletions e triploidyarrow_forward
- Normal (nonmutant) tumor-suppressor genes often functiona. as negative regulators of cell division.b. in the maintenance of genome integrity.c. in the stimulation of cell division.d. as both a and b.arrow_forwardWhich of the following mutations is MOST likely to cause cancer? A) a mutation that causes a cyclin gene to be expressed at all times during the cell cycle B) a mutation that causes an oncogene to be turned off so that no protein is made C) a mutation that causes a Cdk gene to be turned off so that no protein is made D) a mutation that causes a tumor suppressor gene to be over-expressedarrow_forwardWhich of the following best describes a gene that codes for a tumor-suppressor protein? a. One that helps to prevent progression through the cell cycle. b. One that helps prevent apoptosis. c. One that codes for a DNA repair enzyme. d. One that supports part of a growth factor signaling pathway.arrow_forward
- Which of the following types of mutations would be advantageous to a cancer cell (select all that apply)? A. An inactivating mutation in a tumor suppressor gene B. Methylation of the promoter of a tumor suppressor gene C. An inactivating mutation in an oncogene D. Mutation that inactivated DNA repair gene E. An inactivating mutation in an oncogenearrow_forwardDiscuss the interplay between genetics and environment in the development of cancer (it would be helpful to focus on one tumor suppressor/disease to narrow the scope of the discussion). Which factor (genetics or environment) is playing a larger role within your chosen context? Justify your argument.arrow_forwardWhich of the following demonstrates the link between oncogenes and cancer? a.Oncogenes do not have mutations that increase the activity or number of molecules that stimulate mitosis. b.Oncogenes produce molecules that inhibit mitosis. c.They are genes that transform tumor cells into normal cells. d.The mutations in oncogenes increase the activity or number of molecules that stimulate mitosis, leading to irregular cell division.arrow_forward
- 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.arrow_forwardSome cancers have been treated with drugs that demethylate DNA.Explain how these drugs might work. Do you think the cancer-causinggenes that responded to the demethylation are likely to have beenoncogenes or tumor-suppressor genes? Explain your reasoning.arrow_forwardWhich of the following effectively describes the situation of someone with an inherited predisposition to cancer such as familial adenomatous polyposis or BRCA-associated familial breast cancer? Choose all that apply a) If they get malignant cancer, somatic mutations will not have been a factor b) Their cancer will most likely arise in their germ cells, not their somatic cells c) None of the answers effectively describes the situation d) Every cell of their body contains a gain-of-function allele of an oncogene e) Most cells in their body contain multiple cancer-causing mutations f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor genearrow_forward
