Lactose is absent in the cell. An operon is a clump of genes managed by a singular promoter. In the lac operon model, the genes within the operon will be expressed if. Web the lac operon is a good example of the negative control (negative regulation) of gene expression in that bound repressor prevents transcription of the. It is switched off when the rna polymerase binds to the. Promoters are a region of dna where. Web the lac operon is used for the transportation and metabolization of lactose.
