Likewise, prokaryotic cells can turn genes on and off based on environmental factors. Sometimes related genes are grouped together with one switch. This group of genes, along with the sections of DNA that regulate them, is called an operon. Control of Gene Expression in ProkaryotesGene expression refers to genes being ‘turned on’ and producing a product. The product could be an enzyme, a structural protein, or a control molecule. Studies of gene expression typically measure the production of mRNA. Most mechanisms that control gene expression do so by controlling transcription, the synthesis of mRNA.Prokaryotic Gene Regulation. 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).Control of Gene Expression in Prokaryotes How do prokaryotes use operons to control gene expression? Why? Houses usually have a light source in every room, but it would be a waste of energy to leave every light on all the time, so there are switches to turn off the lights in rooms that are not in use.
