Answer:
Operon is the DNA segments with transcribed genes as single unit.
Step-by-step explanation:
An operon is a bunch of practically related genes that are constrained by a common administrator. Operon comprise of different genes gathered with a promoter and an operator. Operon are available in prokaryotes (microbes and archaea), however, they are missing in eukaryotes.
In certain circumstances, numerous operon are constrained by the equivalent administrative protein; in these cases, the operon structures a regulon. Operon was first distinguished as a method of quality articulation control in 1961 by François Jacob and Jacques Monod.
