Question

Quizplus · Accepted Answer

An operon is a functional unit of DNA that consists of multiple genes controlled by a single promoter and operator region. This allows for the coordinated regulation of gene expression in response to environmental changes. The regulator and inducer can also play a role in regulating the operon, but they are not specific to the simultaneous regulation of multiple coding regions. The promoter and operator regions are important for regulating the transcription of the genes within an operon, but they do not enable the simultaneous regulation of multiple coding regions on their own.
