What does the operator control?
Gene expression
Cell division
Protein folding
DNA repair
Answer
Gene expression is controlled by operators, which are specific DNA sequences located near the promoter region of a gene. Operators bind to repressor proteins, which prevent RNA polymerase from transcribing the gene. When an inducer molecule binds to the repressor protein, it causes a conformational change that releases the operator, allowing RNA polymerase to transcribe the gene.
