Question

Refer to the image of the bacterial plates below. A few bacterial strains were spotted on a master plate that contained minimal media and the amino acids tryptophan, lysine, arginine. The strains were then replica plated onto plates with minimal media and various combinations of amino acids. Use these images to determine the genotypes of the bacterial strains. Master Plate B A C Lys, Trp Arg, Trp Arg, Lys What is the genotype of bacterial strain B? Select one: a. Lys+ Arg+ Trp+ b. Lys+ Arg- Trp+ c. Lys+ Arg+ Trp- d. Lys- Arg+ Trp+ e. Lys- Arg+ Trp- f. Lys- Arg- Trp-
