- Lord Voldemort seeks immortality to rule over the wizarding and muggle world forever. As his loyal servant, you point out to him that in his quest for horcruxes, he has forgotten about the importance of avoiding cancer as he ages. Specifically, which of the following magical spells should he learn to use? A spell that… decreases DNA repair accuracy during mitosis makes him smaller (e.g., fewer total cells) Increase the rate of mitosis increases his number of copies of p53 all of the above none of the abovearrow_forwardWhat is the difference between a proto-oncogene and an oncogene? a. oncogenes cause benign tumors (polyps), proto-oncogenes cause malignant tumors b. oncogenes transform cells to hyperproliferation, proto-oncogenes have a normal cellular role c. oncogenes have undergone post-translational modification, proto-oncogenes have not d. oncogenes have undergone intron splicing, proto-oncogenes have notarrow_forwardWhy are dominant mutations in proto-oncogenes generally not inherited? A. Inherited mutations in proto-oncogenes would not affect cell division rate B. Inherited mutations in proto-oncogenes would decrease cell division rate and no viable embryo would form C. Inherited mutations in proto-oncogenes would increase cell division rate and no viable embryo would form D. Dominant mutations in proto-oncogenes are always inheritedarrow_forward
- 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 regulatorsarrow_forwardFigure 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?arrow_forwardFigure 10.14 Human papillomavirus can cause cervical cancer. The virus encodes E6, a protein that binds p53. Based on this fact and what you know about p53, what effect do you think E6 binding has on p53 activity? E6 activates p53 E6 inactivates p53 E6 mutates p53 E6 binding marks p53 for degradationarrow_forward
- The Adaptive Immune Response Is a Specific Defense Against Infection Researchers have been having a difficult time developing a vaccine against a certain pathogenic virus as a result of the lack of a weakened strain. They turn to you because of your wide knowledge of recombinant DNA technology and the immune system. How could you vaccinate someone against the virus, using a cloned gene from the virus that encodes a cell-surface protein?arrow_forwardWhich of the following demonstrates the link between oncogenes and cancer? The mutations in oncogenes increase the activity or number of molecules that stimulate mitosis, leading to irregular cell division. Oncogenes produce molecules that inhibit mitosis. Oncogenes do not have mutations that increase the activity or number of molecules that stimulate mitosis. Oncogenes are genes that transform tumor cells into normal cells.arrow_forwardRelatively few inherited forms of cancer involve the inheritance of mutant oncogenes. Instead, most inherited forms of cancer are defects in tumor-suppressor genes. Give two or more reasons why inherited forms of cancer seldom involve activated oncogenes.arrow_forward
- The palladin gene, which plays a role in pancreatic cancer (see theintroduction to this chapter), is said to be an oncogene. Which of itscharacteristics suggest that it is an oncogene rather than a tumorsuppressorgene?arrow_forwardWhy does a single mutation in a proto-oncogene, turning it into an oncogene potentially lead to a cancerous phenotype, while it takes two mutations in tumor suppressor genes to lead to a cancerous phenotype?arrow_forwardIn some cancer cells, a specific gene has been duplicated many times. Is this gene likely to be an oncogene or a tumor-suppressor gene? Explain your reasoningarrow_forward
