Strain SD+HIS 24 and 48hrs SD+HIS+URA SD+HIS+LEU SD+HIS+URA+LEU A +/+ +/+ +/+ +/+ B +/+ +/+ -/- +/+ C +/+ -/- +/+ +/+
1) How many different auxotrophic phenotypes are represented in your collection of three yeast strains?
2)Suppose you had a fourth yeast strain that was haploid and unable to synthesize the amino acid, arginine. If you replica plated the strain onto the same kinds of plates that you used in this experiment, on which plates would this strain be able to grow? Explain your answer.
