Transcription of the Genes in an Inducible Operon

Question

Transcription of the genes in an inducible operon
A)occurs continuously in the cell.
B)starts when the pathway's substrate is present.
C)starts when the pathway's product is present.
D)stops when the pathway's product is present.
E)does not result in the production of enzymes.

Accepted Answer

Inducible operons are only transcribed when the substrate of the pathway is present. This allows the cell to conserve resources by only producing enzymes when they are needed.
