Question 11
(Multiple Choice)
You are interested in the regulation of gene Q.Proteins G, H, and J are proteins that are important for regulating gene Q, and bind to its promoter region in a sequence-specific fashion.Proteins G and H both bind to site "A" but cannot bind to site "A" at the same time.Protein J binds to site "B" on the promoter.The promoter region is diagrammed in Figure 8-20. 
Table 8-20 Which proteins are likely to act as gene activators? A)G B)H C)J D)both H and J" class="answers-bank-image d-block" loading="lazy" > Figure 8-20
You develop a cell-free transcriptional system to study the effects of proteins G, H, and J on the transcription of gene Q.Using this system, you can examine the effects of adding these proteins to the transcriptional system in equal amounts and measuring how much gene Q is produced.When you add these proteins to the system, you get the results shown in Table 8-20.
