It prevents fusion with the cell membrane. It binds to neuraminidase. It mimics a guanine rung. 2. Only immune system cells have MHC-2 receptors.1 True False 3. There is just one type of influezna vaccine.1 True False 4. There are still some viruses for which we have neither vaccine nor anti-viral medicine.1 True False 5. The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False 6. Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False 7. Which researcher used chemicals to damage the polio virus?1 Sabin Salk 8. Immune cells must have whole virus capsids in order to make antibodies.1 True False 9. What is the purpose of an adjuvant?1 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. To be a preservative that will increase the shelf life of the vaccine. 10. Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False 11. Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False 12. 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 acquiring more protein tools inside their capsids. By changing their genomes from RNA to DNA, or vice versa. 13. What does the word “attenuated” mean?1 mutated killed recycled weakened 14. Only B cells can become memory cells.1 True False 15. Sabin knew exactly how his vaccine worked.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
