Detailed explanation-1: -Final answer: Enhancer is not a part of an operon.
Detailed explanation-2: -In the Operon Model, the regulatory genes are those that code for the production of regulatory proteins. For instance, the regulatory gene in lac operon is the lac I gene that codes for the lac repressor. The repressor protein binds to operator gene, which consequently prevents the production of a specific enzyme.
Detailed explanation-3: -Bacterial genes are often found in operons. Genes in an operon are transcribed as a group and have a single promoter. Each operon contains regulatory DNA sequences, which act as binding sites for regulatory proteins that promote or inhibit transcription.
Detailed explanation-4: -A typical operon consists of a group of structural genes that code for enzymes involved in a metabolic pathway, such as the biosynthesis of an amino acid.
Detailed explanation-5: -Components of operon are regulator, promoter, operator and structural genes.
