Activator proteins A and B are required to express gene X An

\"Activator proteins A and B are required to express gene X. Analysis of the DNA upstream from the gene X promoter identified an 18 bp sequence with near twofold symmetry that is required for activation. Purification of the gene A and gene B products showed that both proteins form homodimers, but neither the A nor the B homodimer binds the 18 bp site. What are the possible functions of the A and B activators with respect to the 18 bp site? Propose a test of one of your ideas.\"
