Question

Quizplus · Accepted Answer

The operator is the site on the DNA where the repressor molecule binds, which controls the expression of genes in prokaryotic and eukaryotic organisms. The binding of repressor to the operator site prevents the binding of RNA polymerase to the promoter region, thereby inhibiting the transcription of genes.

The Operator __________
