Above we probed the error with respect to the hexamer exposed at the fiber end. We also probed, for cases i-iv, how similar the newly formed hexamer replicators were to the original fiber seed. The mutational distance between the composition of the new hexamer and the original seed composition was quantified analogues to how Hamming's distance is defined for nucleic acids, and is given by: M = │nA new -<nA seed >│ (3) where nA new is the number of A's in the new hexamers and <nA seed > is the average number of A's in the seed.
