Abstract:
Controversy surrounds the perceived absence of a relationship between DNA polymerase fidelity (kinetic discrimination) and free energy changes determined from DNA melting studies (thermodynamic discrimination). Thermodynamic discrimination together with aqueous solvent effects can account for kinetic fidelities on the order of those observed experimentally.
