Vedclass · Answer

(B) In the Operon model,the regulator gene codes for a protein called the repressor protein.This repressor protein binds to the operator site of the operon.When the repressor is bound to the operator,it physically blocks $RNA$ polymerase from transcribing the structural genes into $mRNA$.Therefore,the regulator gene controls the expression of the operon by inhibiting the transcription of $mRNA$.

In the Operon concept,the regulator gene regulates chemical reactions in the cell by:
