Molecular Basis of Inheritance

In an E. coli strain the i gene gets mutated and its product cannot bind the inducer molecule. If the growth medium is provided with lactose, what will be the outcome?

  1. A.RNA polymerase will bind the promoter region
  2. B.Only the z gene will get transcribed
  3. C.z, y, a genes will be transcribed
  4. D.z, y, a genes will not be translated

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
