Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False 3. Which researcher used chemicals to damage the polio virus?1 Salk Sabin 4. What is the purpose of an adjuvant?1 To add an additional chemical that will help to poison the virus. To prevent other immune cells from hindering the antibody repsonse by T and B cells. To get other types of immune cells to help with the antibody repsonse by T and B cells. To be a preservative that will increase the shelf life of the vaccine. 5. How can viruses become resistant to anti-viral medicines?1 By changing their genomes from RNA to DNA, or vice versa. Through mutations to the genome which cause tiny changes in the shapes of their proteins. By acquiring more protein tools inside their capsids. Their protease "scissors" develop the ability to shred the medicine molecules. 6. Sabin knew exactly how his vaccine worked.1 True False 7. What does the word “attenuated” mean?1 killed recycled mutated weakened 8. There is just one type of influezna vaccine.1 True False 9. Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False 10. There are still some viruses for which we have neither vaccine nor anti-viral medicine.1 True False 11. Which one is true of Acyclovir?1 It prevents fusion with the cell membrane. It blocks the M2 channel. It mimics a guanine rung. It binds to neuraminidase. 12. Only B cells can become memory cells.1 True False 13. The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False 14. Immune cells must have whole virus capsids in order to make antibodies.1 True False 15. Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False VIRUSES lesson 9: The Body Fights Back VIRUSES: Bonus info and extra resources Back to: VIRUSES lesson 10: Vaccines and anti-virals
