56. Various techniques have been developed to isolate strains of bacteria carrying a particular
mutation. One of them is, bacteria containing wild-type cells and cells of a desired mutant are
grown on a medium lacking the nutrient for which the desired mutants are auxotrophic but
containing an antibiotic that only kills growing cells. In this environment,

58. You expose a tube of bacteria to ultraviolet radiation to induce mutations. You then
spread the bacteria on a plate containing media with all known required nutrients and wait
until separate colonies form. Finally, you use replicate plating to transfer a print of this plate
to an additional sterile plate containing minimal media plus a known required nutrient for the
bacteria. Based on this protocol, colonies growing on the plate with minimal media would
