If a researcher moves the promoter for the lac operon to the region between the beta galactosidase (lacz) gene and the permease (lacY) gene, which of the following results would be most likely? O RNA polymerase will no longer transcribe permease. O The operon will still transcribe the lacZ and lacY genes, but the MRNA will not be translated. Beta galactosidase will not be produced. O The three genes of the lac operon will be expressed normally.
