Using the Holliday junction DNA substrate pictured below (5?- 32 P end labeled), propose an assay that researchers may have used to determine RuvA protein binding to the DNA substrate. Propose a modification to the DNA substrate to use as a negative control that demonstrates an aspect of the specificity of RuvA binding. (A, B, C, and D are labels for the unique ssDNA fragments that were used to assemble this substrate.)
