Distinguish between the functions of the basal apparatus, activators, and coactivators
What will be an ideal response?
Ans: All of these proteins participate in the initiation of transcription. The components of the basal apparatus bind to the promoter along with RNA polymerase. Activators are transcription factors that bind to the promoter and/or enhancers to facilitate the binding of the basal apparatus. Coactivators do not bind to the promoter itself, but facilitate connections between activators and the basal apparatus.
