You are given a constitutive mutant, but you are not told whether it is constitutive due to a repressor mutation (i-) or an operator mutation (o^c). Determine what could be added to the system that would allow you to determine the difference between the two mutants. You will add the same thing to each and indicate the results of the experiment.
Mutant Phenotype Mutant Add to system on a plasmid Resulting phenotype i- Constitutive i-
