What role does an operator play in gene expression?
What role does an inducer play in gene expression?

An operator is the section of DNA where RNA polymerase begins transcription of the DNA into messenger RNA. An inducer binds to a repressor protein causing it to lose its grip on the operator thus allowing transcription to be initiated.
