Question

Quizplus · Accepted Answer

An operon is a single DNA unit that contains multiple genes and regulatory elements that enable the simultaneous regulation of those genes in response to environmental changes. This includes the presence of an operator, which controls access of RNA polymerase to the genes, and a regulator, which can bind to the operator and regulate the expression of the operon. An inducer is a molecule that can bind to the regulator and induce gene expression, but it is not specific to an operon. A promoter is a DNA element that initiates transcription of a single gene, but it does not enable the coordinated regulation of multiple genes.
