Question 5 Your friend is an amateur mushroom hunter. He accidentally eats an Amanita phalloides "Death Cap" mushroom and becomes very ill. You recall from university that this mushroom is toxic because it contains a aminitin, a noncompetitive inhibitor of RNA polymerase. Which of the following hypothetical treatments (if they were possible) would NOT help your friend? Select all best answers for full credit Injecting more RNA polymerase into his cells. Injecting a drug that binds the enzyme-binding region a...
