Solutions For An Introduction to Genetic Analysis Chapter 12 Problem 33P

The following diagram shows enhanceosome, recruiting RNA polymerase to promoter of YSP.

Where, A represents TFA; B represents TFB; C represents TFC and X represents CRX. The complex formed as a result of the complex formed as a result of the transcription factors A, B and C. Moreover, it recruits co-activator CRX (X) to the RNA polymerase enzyme.

Hence, the enhanceosome is located at about 10kb from the coding region of the gene, thus making sure that the movement of enhanceosome would not edit the coding region.
