Part E Choose the explanation why certain mutations in the regulator gene (

) of the lac system result in maximal synthesis of

-galactosidase, permease, and transacetylase even in the absence of the inducer (lactose). Such mutations provide modified proteins that associate with the promoter activating transcription. Such mutations provide modified proteins that associate with the promoter not allowing transcription to occur. Such mutations provide modified proteins that associate with the operator activating transcription. Such mutations provide modified proteins that are unable to associate with the operator to shut off transcription.
