A mutant is found in which the operon is uninducible. Assuming the affected gene makes a protein, what kind of transcriptional regulator could the gene produce?

You don't specify what type of mutant.

If it is deletion or loss-of-function mutation then were are talking about an activator. (No functional activator is in the cell so the operon cannot be expressed).

However the protein could be a repressor and the mutation could be such that it doesn't allow e.g. the binding of an inducer or the post-translational modification of the repressor that would relieve repression and allow expression of the operon under the expected conditions. Or it could be a mutation that locks the repressor in its active (repressing) form so that it represses the operon under all conditions.

I don't know, but i bet you're taking genetics at Rutgers
