operon is a group of functionally related genes which act as single transcriptional unit
operon consists of structural gene, regulatory gene, promotor, operator, and initiator region
operon - inducible and repressible operon
Inducible (positive regulator) - regulatory gene act as activator ➡️ RNA polymerase bind to promoter🔄 switch on the transcription
Repressible (Negative regulator) - regulatory gene act as Repressor ➡️ RNA polymerase doesn't bind to promoter🔄 switch off the transcription
L Arabinose operon is present in E.coli required for the metabolism of L arabinose
