Cas9 on Template Orientation (image) University of Illinois at Chicago Share Print E-Mail Caption UIC researchers show persistent Cas9 binding to a double strand break causes CRISPR genome editing to fail about 15 percent of the time. When RNA polymerases collide with Cas9 from one direction (template orientation), they can dislodge Cas9 and increase genome editing efficiency.
