SOLVED: Lac operonWhat happens if the promoter and operator in the lac operon are reversed? Does the rate of galactosidase increase, decrease, or remain unchanged and why? What happens if there is a silent mutation of the regulator gene in the lac operon? What happens if there is a missense mutation of the regulator gene in the lac operon? What happens if there is a nonsense mutation of the regulator gene in the lac operon? Could a mutation of the regulator gene be present without producing a ch

SOLVED: 1. The lac operon in E. colicomprises three structural genes, lac Z, lacY,and lacA. It is regulated by both positive and negativemechanisms, involving binding of both a repressor protein and thecatabolite activator protein (CAP). Transcription of theoperon gives a polycistronic mRNA encoding the three enzymes. Under the following nutritional conditions, indicate whether or notthe repressor and the CAP are bound by drawing them in on theappropriate regions of the operon. Indicate, as

SOLVED: The lac operon is a coordinately regulated group of genes (lacZ, lacY, lacA) that are required for lactose digestion in E. coli. Based on the figure:a. Identify the conditions for when the lac operon is switched "on".b. Explain the role of the repressor and the operator in switching the lac operon to "on".Lac operonDNARNA polymerasemRNAProteinGalactoseTransacetylaseAllolactose (inducer)Inactive repressor
