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