Fig 5. Elongation under the influence of cooperative motifs.

(a) Motif pair A: 11110 and B: 00001 successfully cooperate by building each other’s precursors. The values on the x-axis show whether the particular monomer was added under the influence of motif A, motif B, or neither (denoted by X). (b) Same plot for motif pair A: 01111 and B: 10000, shows that such cooperative relationship does not exist for this pair, hence they do not exhibit selective advantage through biasing the monomer balance towards the main element of their partner. N = 100, M = 100, r = 0.05, and maximum strand length 7 for all runs. Only patterns above a frequency of 0.005 are shown. Average of 15 trials.
