  In the diagram above, there are two hypothetical models for binding of core eukaryotic transcription factors in a previously unstudied organism you discovered. These transcription factors will recruit the RNA polymerase II to begin polymerizing mRNA. In panel A, you see a dimer of protein “X” which associates symmetrically with the DNA and then binds to two polypeptides of the “Y” protein, one on each end. In panel B, there are three proteins “L”, “M” and “N” that bind to the DNA asymmetrically as shown. Your colleague Bill favors model A and your colleague Sally favors model B. Who has the right model and why? What is fundamentally problematic with the other one?
