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