Question:
Consider the following complementation test strains and their results. The unknown his mutants have single mutations in different his genes.
Tested strains:
Strain 1: his 5 Strain A: his #?
Strain 2: his 1 Strain B: his #?
Strain 3: his 7 Strain C: his #?
Results: Media: SD + histidine
Strain 1 X A: growth Strain 2 X A: no growth Strain 3 X A: no growth
Strain 1 X B: growth Strain 2 X B: growth Strain 3 X B: growth
Strain 1 X C: growth Strain 2 X C: no growth Strain 3 X C: no growth
Results: Media: SD
Strain 1 X A: growth Strain 2 X A: no growth Strain 3 X A: no growth
Strain 1 X B: no growth Strain 2 X B: growth Strain 3 X B: growth
Strain 1 X C: growth Strain 2 X C: no growth Strain 3 X C: no growth
What can you conclude from the test results? Explain your reasoning in detail.
Next to each mating, write the known diploid genotype. Assume the same TRP/trp and ADE/ade mutations for all strains just like the strains used in the experiment (from the lab manual).
