a

Calculated as (kp/Kd, dNTP)normal/(kp/Kd, dNTP)damaged.

b

The values are from Supplementary Table 2 using control 26mer DNA template.

c

Calculated as (kp/Kd, dNTP)incorrect/[(kp/Kd, dNTP)correct + (kp/Kd, dNTP)incorrect].

d

Calculated as Fidelitydamaged/Fidelitynormal.

e

Calculated as ((kp/Kd, dNTP)damaged/[Σ(kp/Kd, dNTP)damaged])×100.

All given errors were derived from data fitting.
