Preferred Label : operon;
IUPAC definition : A functional unit consisting of a promoter, an operator and a number of structural
genes, found mainly in prokaryotes. The structural genes commonly code for several
functionally related enzymes, and although they are transcribed as one (polycistronic)
mRNA each is independently translated. In the typical operon, the operator region
acts as a controlling element in switching on or off the synthesis of mRNA.;
