The mechanisms that lead to enhanced replication fidelity and error correction, as we hypothesized above, rely critically on the ability of replicator assemblies to exhibit selectivity in the binding of precursors. We first confirmed experimentally that such selectivity can indeed occur using centrifugation experiments. We then assessed the extent to which selective precursor binding can improve replication fidelity and correct errors using a computational model. Note that assessing these effects experimentally would require control experiments where no precursor aggregates on replicator assemblies are formed. Unfortunately, we are unable to switch off the binding of precursors, precluding a direct experimental assessment of fidelity enhancement and error correction.
