Question

Write explanatory notes on the following with respect to operon concept – Repressor, Co-
repressor, structural gene.

Answer 1

Hello!

Repressor -

Repressor of the operon is synthesized from i Gene, when the glucose is present in the medium.

Repressor binds to operater region (O) and prevents RNA polymerase from transcribing to the operon.

Co-Repressor -

It is a molecule that binds to the Repressor and hence named co-repressor

Structural Gene -

It codes for any RNA or Protein product.
They are the fragments of DANA,which transcribe mRNA for polypeptide synthesis.

Thanks :)
