Vedclass · Answer

(D) In bacterial gene regulation,specifically in the operon model,the accessibility of the promoter region to $RNA$ polymerase is controlled by the interaction of regulatory proteins (repressors) with specific $DNA$ sequences known as operators. When a repressor protein binds to the operator,it physically blocks $RNA$ polymerase from transcribing the structural genes,thereby preventing the synthesis of $mRNA$.

The accessibility of promoter regions of bacterial $DNA$ in many cases is regulated by the interaction of proteins with sequences termed:
