#Unit 3. Fundamental Processes
The sequence of transcriptional activation events at a typical Pol II promote
I- Mediator facilitates the binding of TBP (or TFIID) and TFIIB, and the other basal transcription factors and Pol II then bind.
II- Activators bind the DNA.
III-The activators recruit the histone modification/nucleosome remodeling complexes and a coactivator such as Media.
IV- Phosphorylation of the carboxyl-terminal domain (CTD) of Pol II leads to transcription initiation.
