(A) Type 1 transcription. RNA Polymerase is freely soluble and is recruited to gene promoters for transcriptional activation.
(B) Type 2 transcription. RNA Polymerase is fixed and single mobile gene interacts with fixed e-Pol II for transcriptional activation.
(C) RNA Polymerase is fixed and mobile gene cluster simultaneously interacts with fixed RNAP for transcriptional activation.
(D) THERE IS MORE TO THIS FIGURE AS INDICATED. WE CAN PULL FIGURE FROM your paper as long as we cite and/or modify slightly. OR WE CAN SPLIT FIGURE 1, depends how it looks.
