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 below.You develop a cell-free transcriptional system to study the effects of proteins G, H and J on the transcriptional 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 the table.Which proteins are likely to act as gene activators?
