Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False 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 The goal of an anti-viral medicine is to block or break a viral part without harming the body cell.1 True False Immune cells must have whole virus capsids in order to make antibodies.1 True False There is just one type of influezna vaccine.1 True False Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False How can viruses become resistant to anti-viral medicines?1 By acquiring more protein tools inside their capsids. Their protease "scissors" develop the ability to shred the medicine molecules. By changing their genomes from RNA to DNA, or vice versa. Through mutations to the genome which cause tiny changes in the shapes of their proteins. Which one is true of Acyclovir?1 It mimics a guanine rung. It blocks the M2 channel. It binds to neuraminidase. It prevents fusion with the cell membrane. Only B cells can become memory cells.1 True False Sabin knew exactly how his vaccine worked.1 True False 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. What does the word “attenuated” mean?1 killed weakened recycled mutated Which researcher used chemicals to damage the polio virus?1 Salk Sabin Only immune system cells have MHC-2 receptors.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
