Web12 de set. de 2024 · September 12, 2024 by Alexander Johnson. Replicative polymerases achieve high fidelity of DNA replication by employing several mechanisms: (1) sensing proper geometry of correct base pair, (2) slowing down catalysis in case of a mismatch, and (3) partitioning the mismatched primer to exonuclease active site. Table of Contents show. Webduring DNA replication. When DNA is synthesized in the absence of en zymes, such errors happen about once in every 100 bases.
