What does the word “attenuated” mean?1 weakened killed mutated recycled Only B cells can become memory cells.1 True False Polio’s genome has been completely mapped out, down to every last rung of its RNA.1 True False Sabin knew exactly how his vaccine worked.1 True False Only guanine rungs can be mimicked by anti-viral analogue medicines.1 True False Which researcher used chemicals to damage the polio virus?1 Sabin Salk How can viruses become resistant to anti-viral medicines?1 By acquiring more protein tools inside their capsids. By changing their genomes from RNA to DNA, or vice versa. Their protease "scissors" develop the ability to shred the medicine molecules. Through mutations to the genome which cause tiny changes in the shapes of their proteins. Sabin’s attenuated polio vaccine could still infect intestinal cells.1 True False Immune cells must have whole virus capsids in order to make antibodies.1 True False Only immune system cells have MHC-2 receptors.1 True False There are still some viruses for which we have neither vaccine nor anti-viral medicine.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 get other types of immune cells to help with 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. 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 Which one is true of Acyclovir?1 It blocks the M2 channel. It prevents fusion with the cell membrane. It binds to neuraminidase. It mimics a guanine rung.
