BIOL 230 Lecture Guide - Activator Protein in the Absence of an Inducer

Fig. 6: An Activator Protein in the Absence of an Inducer

1. Transcription and translation of the regulatory gene produces an inactive activator protein.
2. The inactive activator protein is unable to bind to the activator binding site.
3. As a result, RNA polymerase is unable to bind to its promoter.
4. The structural gene is not transcribed and no enzyme is made.
