N6-methyladenine (6mA) is reported as a potential epigenetic marker in eukaryotic genomes. However, accurate identification of the location of 6mA in DNA remains a challenging task. Here, we show that Ag<sup>+</sup> can selectively stabilize the A-C mismatch and efficiently promote primer extension. In contrast, the complex of 6mA-Ag<sup>+</sup>-C is instable and therefore cannot be recognized by DNA polymerases, resulting in the termination of primer extension. Based on this finding, we success ...[more]
