Suppose that a scientist is studying a bacteriophage that infects and induces lysis of e. coli. he generated several mutant bacteriophage that are unable to lyse e. coli. to better understand the mechanism of action of the mutant phage, he coinfects e. coli with pairs of mutant bacteriophage to assay for bacterial lysis. if mutants 1 and 2 are both in one cistron and mutants 3 and 4 are both in a different cistron, determine the outcome for each experimental coinfection. outcome mutant mutant 2 23 lysis answer bank no lysis no lysis undetermined lysis lysis lysis
