ResetHelp If repressor inhibits RNA polymerase binding to the promoter, then one way to demonstrate this would be to incubate a plasmid containing the lac operon with lac If repressor inhibits R N A polymerase binding to the promoter, then one way to demonstrate this would be to incubate a plasmid containing the lac operon with lac blank. Then add R N A polymerase and subject the mixture to sucrose gradient centrifugation and analyze each fraction for R N A polymerase and repressor, using antibodies to the two proteins. A simpler method would be to analyze the mixture by gel electrophoresis and probe the gel ( blank ) with antibodies to R N A polymerase and repressor ( blank ). Another experiment could involve footprinting; carry out blank assays, asking whether repressor inhibits R N A polymerase binding or vice versa..
