Only immune system cells have MHC-2 receptors.1 True False Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False What does the word “attenuated” mean?1 mutated weakened killed recycled Sabin knew exactly how his vaccine worked.1 True False How can viruses become resistant to anti-viral medicines?1 By changing their genomes from RNA to DNA, or vice versa. Their protease "scissors" develop the ability to shred the medicine molecules. By acquiring more protein tools inside their capsids. Through mutations to the genome which cause tiny changes in the shapes of their proteins. Which researcher used chemicals to damage the polio virus?1 Salk Sabin Immune cells must have whole virus capsids in order to make antibodies.1 True False Which one is true of Acyclovir?1 It mimics a guanine rung. It binds to neuraminidase. It prevents fusion with the cell membrane. It blocks the M2 channel. What is the purpose of an adjuvant?1 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. 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. Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False There are still some viruses for which we have neither vaccine nor anti-viral medicine.1 True False Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False Only B cells can become memory cells.1 True False 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
