In a genetics lab, kim and maria infected a sample from an e. coli culture with a particular virulent bacte- riophage. they noticed that most of the cells were lysed, but a few survived. the survival rate in their sample was about 1 x 10-4. kim was sure the bacte riophage induced the resistance in the cells, while maria thought that resistant mutants probably already existed in the sample of cells they used. earlier, for a different experiment, they had spread a dilute suspension of e. coli onto solid medium in a large petri dish, and, after seeing that about 105 colonies were growing up, they had replica-plated that plate onto three other plates. kim and maria decided to use these plates to test their theories. they pipette a suspension of the bacteriophage onto each of the three replica plates. what should they see if kim is right? what should they see if maria is right?
