Detailed explanation-1: -An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
Detailed explanation-2: -The operon: a group of genes with expression coordinated by an operator.
Detailed explanation-3: -An operon is a group of structural genes whose expression is coordinated by an operator. The repressor encoded by a regulatory gene binds to the operator and represses the transcription of operon. In the presence of inducer, the repressor is inactivated and dissociates from operator to express the operon.
Detailed explanation-4: -An operon is the structure of a cluster of genes in the genome of an organism. The operons are comprised of many genes which encode for different proteins or products. The polycistronic mRNAis synthesized from which many polypeptides can be produced.
Detailed explanation-5: -An operon is a group of genes under the control of a single promoter.
