Can eukaryotes have operons

WebOperons are common in prokayotes, specifically bacteria, but have also been discovered in eukaryotes. Operons consist of a promoter, which is recognized by the RNA polymerase, an operator, a segment of DNA in which a repressor or activator can bind, and the structural genes that are transcribed together.
