The reverse exchange between Polδ and Polη in the presence of either PCNA or K164–Ub–PCNA. (A) Reaction sequence of reverse exchange between Polη and Polδ is shown. (B) Alkaline agarose gel electrophoresis of the DNA synthesis product by Polδ in the presence of increasing concentration of Polη is shown. (C) The quantification of DNA product as shown in B is depicted.
