3 Structural gene clusters are coordinately controlled. 1  An operon is a unit of bacterial gene expression and regulation, including structural genes and control elements in DNA recognized by regulator gene product(s).acterial structural genes are often organized into clusters that include genes coding for proteins whose functions are related.
In constitutive mutants, the lac operon genes are continuously transcribed. A mutant regulator gene (lacI -) produces a defective repressor that cannot bind to the operator. A mutant operator region (lacO c) is defective in that the repressor cannot bind and thus transcription cannot be shut off.Both types of mutants have the same constitutive phenotype. mutant regulator gene (lacI -) produces a defective repressor that cannot bind to the operator.
