In the lac operon model, the genes within the operon will be expressed if. Promoters are a region of dna where. Web in e.coli and other bacteria, the lac operon is a set of genes with a single promoter that expresses genes for lactose transport and metabolism. Web today, the operon is simply defined as a cluster of genes transcribed into a single mrna molecule. 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. The first operon to be.

C.) the repressor protein has fallen off the molecule. Web the lac operon refers to an operon needed for the transport and metabolism of lactose in escherichia coli. It is switched off when the rna polymerase binds to the. 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. Lactose is absent in the cell. Promoters are a region of dna where. Web the lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.
