Replicative DNA polymerases (DNAPs) have evolved the ability to copy the genome with high processivity and fidelity. Here, the authors present a cryo-EM structure of the DNA-bound PolD–PCNA complex from Pyrococcus abyssi to reveal the molecular basis for the interaction and cooperativity between a replicative DNAP and PCNA.
