1. In the figure below, researchers measured the amount of transcription driven by a promoter that was mutated one base pair at a time. The y-axis shows the amount of transcription, relative to the wild-type promoter, for each mutation. Orange dots indicate 4.0 1.0 -100 -80 -60 -40 -20 20 TAAG 3 GC-rich CAAT box -37 TATA box 01986 AAAS start (+1) Which of the following statements is a conclusion that you can draw from these data? A. Mutations downstream of the transcription start site have a large effect on transcription B. The majority of mutations between the CAAT box and the TATA box have no effect. C. Mutations in the TATA box increase transcription. D. Mutations in the promoter region can increase, decrease or have no effect on transcription. E. B & D are true
