In bacteria and archaea, structural proteins with related functions are usually encoded together within the genome in a block called an operon and are transcribed together under the control of a single promoter, resulting in the formation of a polycistronic transcript (Figure 1).A classic example of repressor control of gene expression, the lac operon, also illustrates another method by which bacteria may control the expression of genes.
