Arrange the following steps in correct order: (TRANSCRIPTION): (I) The nascent RNA separates and RNA polymerase also detaches and thus terminates the process of transcription. (II)RNA polymerase loses the factor, but continues to add ribonucleotides to form RNA. (III) Binding of RNA polymerase to the promoter and its association with initiation factor (sigma) . (IV) The RNA polymerase associates with termination-factor (rho) transiently to stop the transcription process.

RNA polymerase - III synthesize

What is synthesised by RNA polymerase ?

The lac operon consists of a regulation gene and three structural gene. The lactose acts as inducer. In the presence of an Inducer such as lactose, the repressor is in inactivated during the interaction. This allows RNA polymerase access to the promoter and transcription proceeds. The repressor is synthesized which in turn binds with the operator region of the operon and prevents RNA polymerase from transcribing the operon. What provides binding site to RNA polymerase?
