It’s a group of genes from the gDNA (genomic deoxyribonucleic acid) in prokaryotes and some eukaryote organisms. The transcription of the operon simply takes to a polycistronic mRNA (messenger ribonucleic acid) molecule wich is composed by an operator, a promoter and other structural genes. The promoter associated to the operator controls the structural genes expression. The translation of the operon rises to several independent proteins with related metabolic functions.
