Before revision:  We present a rigorous analytical treatment of the  steady-state kinetic equations including higher-order terminal effects , and then apply the results to the fidelity problem of some real DNAPs . Our results show good agreements with previous intuitive estimate of some DNAPs' fidelity under bio-relevant conditions .
