Figure 6From: In silico ribozyme evolution in a metabolically coupled RNA populationThe evolution of the distribution of folding energy. Panels show the distribution of the folding energy of mono-active and functionless (parasitic) replicators at different times: A: t = 0, B: t = 1500, C: t = 2500 and D: t = 1000000. Colour code as in Figure 4. Parameters: h = 3×3, b 2 = 0.05, D = 4.Back to article page
