The diagram (Figure 2) below is a model of how Octl may be involved in the regulation for the lactase gene. 20. On Figure 2 below, label on the diagram the cis-acting element on the lactase gene that Octl and HNF 1 respectively bind. 21. Based on the role of Octl draw the configuration of the transcription initiation complex of the lactose gene. Include in the label the position/location of Oct1, HNF- 1 , and RNA polymerase in the diagram. Figure 2: Model depicting the role of the 13 , 910 enhancer and Octl in the regulation of lactase gene expression. Draw the figure pertaining to question 2 here. .
