. You are working with a specific operon of an organism. The operon contains genes that help to synthesize an amino acid. Your operon has 2 structural genes, an operator, and a promoter. The operon is currently "switched on" and the polymerase is bound, ready for transcription. Draw a model of this operon.

An operon is a regulatory unit consisting of structural genes under the control of a promoter. An operon encodes an mRNA that contains the coding sequence for one or more structural genes. An operon contains several important DNA sequences, including a promoter, structural genes, an operator, and a terminator. During the cycle of lac operon induction and repression, when lactose is present, allolactose is released from the operator, allowing it to bind to the operator site.

A geneticist is studying an inducible operon in a species of bacteria. A regulator gene produces a repressor of the inducible operon. The geneticist isolates several constitutive mutants of this operon. Where might mutations that cause the operon to be constitutively expressed occur? in the repressor gene in the operator region of the operon in the inducer gene in the promoter region of the operon in the coding region of the operon
