DNA constructs (158 bp) with short phasing linkers. The top three DNA constructs contain the AP-1 site (in bold) from the hcg. The center of the AP-1 site is positioned 11, 15, and 19 bp, respectively, from the center of the closest A-tract sequence. The bottom three DNAs are control molecules that contain a single A-tract site in place of the AP-1 site.
