What will be the binding status of regulatory proteins in lac operon when concentrations of both lactose and glucose are very low in the culture medium?
- Only the repressor remains bound to the operator
- Only the cyclic AMP-Catabolic Activator Protein (cAMP-CAP) complex remains bound to the CAP binding site
- Neither the repressor nor cAMP-CAP complex remain bound to their respective binding sites
- Both the repressor and cAMP-CAP complex remain bound to their respective binding sites
