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



Replies:
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.
