Multiple choice

The activator proteins frequently binds with the pertinent DNA segment in ______________________.

  1. positive inducible operons

  2. positive repressible operons

  3. negative inducible operons

  4. negative repressible operons

  5. neutral repressible operons
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In positive repressible operons, the activator proteins are normally bound to the pertinent DNA segment. However, when an inhibitor is bound by the activator, it is prevented from binding the DNA. This stops activation and transcription of the system.
