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