  • Q:

    You want to obtain a spontaneous mutant for Ampicillin resistance in a sample of E. coli. Of the strategies listed below, which is most likely to yield a result the fastest?



    Plate the E. coli on medium with 1 g/mL Ampicillin


    Plate the E. coli on medium with 1 μg/L Ampicillin


    Plate the E coli on a linear gradient medium from a concentration of 1μg/L to a 1 g/mL.


    None; the rise of spontaneous mutants is random and cannot be controlled by any of the methods listed
