Question: Certain E. coli bacteriophages encode a protein called Q, which binds to RNAP shortly after transcription initiation, before 70 is released. Q increases the rate

Certain E. coli bacteriophages encode a protein called Q, which binds to RNAP shortly after transcription initiation, before σ70 is released. Q increases the rate of transcription and renders RNAP resistant to Rho-dependent termination.
(a) Explain how Q could enhance expression of bacteriophage genes.
(b) Explain why the effect of Q depends on its ability to interact with specific DNA sequences, not just RNAP.
