Immune cells must have whole virus capsids in order to make antibodies.1 True False 2. There is just one type of influezna vaccine.1 True False 3. Which researcher used chemicals to damage the polio virus?1 Salk Sabin 4. There are still some viruses for which we have neither vaccine nor anti-viral medicine.1 True False 5. Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False 6. Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False 7. The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False 8. Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False 9. Which one is true of Acyclovir?1 It mimics a guanine rung. It blocks the M2 channel. It binds to neuraminidase. It prevents fusion with the cell membrane. 10. What is the purpose of an adjuvant?1 To be a preservative that will increase the shelf life of the vaccine. To get other types of immune cells to help with the antibody repsonse by T and B cells. 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. 11. How can viruses become resistant to anti-viral medicines?1 By acquiring more protein tools inside their capsids. Through mutations to the genome which cause tiny changes in the shapes of their proteins. By changing their genomes from RNA to DNA, or vice versa. Their protease "scissors" develop the ability to shred the medicine molecules. 12. Only immune system cells have MHC-2 receptors.1 True False 13. Sabin knew exactly how his vaccine worked.1 True False 14. What does the word “attenuated” mean?1 mutated weakened recycled killed 15. Only B cells can become memory 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
