There are still some viruses for which we have neither vaccine nor anti-viral medicine.1 True False 2. How can viruses become resistant to anti-viral medicines?1 Their protease "scissors" develop the ability to shred the medicine molecules. 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. 3. Only immune system cells have MHC-2 receptors.1 True False 4. Which one is true of Acyclovir?1 It blocks the M2 channel. It mimics a guanine rung. It prevents fusion with the cell membrane. It binds to neuraminidase. 5. There is just one type of influezna vaccine.1 True False 6. Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False 7. Immune cells must have whole virus capsids in order to make antibodies.1 True False 8. Which researcher used chemicals to damage the polio virus?1 Salk Sabin 9. What does the word “attenuated” mean?1 recycled mutated killed weakened 10. What is the purpose of an adjuvant?1 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 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. 11. Sabin knew exactly how his vaccine worked.1 True False 12. Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False 13. Only B cells can become memory cells.1 True False 14. The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False 15. Only guanine rungs can be mimicked by anti-viral analogue medicines.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
