What does the word “attenuated” mean?1 weakened mutated recycled killed 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 Sabin knew exactly how his vaccine worked.1 True False Only B cells can become memory cells.1 True False Only immune system cells have MHC-2 receptors.1 True False Which one is true of Acyclovir?1 It prevents fusion with the cell membrane. It blocks the M2 channel. It binds to neuraminidase. It mimics a guanine rung. 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 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’s attenuated polio vaccine could still infect intestinal cells.1 True False What is the purpose of an adjuvant?1 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. To add an additional chemical that will help to poison the virus. To get other types of immune cells to help with the antibody repsonse by T and B cells. There is just one type of influezna vaccine.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 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
