Statement of Purpose
The purpose of this experiment was to determine the complementation of product in
the histidine pathway. Strains of MAT-a and MAT- were mated in this experiment. As
known, each MAT-a strain contains a known auxotrophic mutation, while
Outline of Procedures:
1. After assignment of two primer pairs, take 6 200 microliter PCR tubes and 6 labels, and
fill out labels as shown, where x and y indicate the 2 primer pairs you were assigned.
2. Add 50 microliters of correct PCR cocktail
1. A number of lac- mutants from Experiment 2 will be tested to see if they are suppressed
by one or more amber suppressors.
2. Each lac- mutant will be mated to F- strains with a deletion of the lac-pro region. The Fstrains carry a different sup
A saturated liquid culture of the diploid strain will be diluted and plated unto YPD plates.
The plates were exposed to UV light to increase the frequency of mitotic recombination in the
cells on the plate then incubated for three or more days to allow gr
