Emergence of information transmission in a prebiotic RNA reactor

Title:Emergence of information transmission in a prebiotic RNA reactor
Creators Name:Obermayer, B. and Krammer, H. and Braun, D. and Gerland, U.
Abstract:A poorly understood step in the transition from a chemical to a biological world is the emergence of self-replicating molecular systems. We study how a precursor for such a replicator might arise in a hydrothermal RNA reactor, which accumulates longer sequences from unbiased monomer influx and random ligation. In the reactor, intra- and intermolecular base pairing locally protects from random cleavage. By analyzing stochastic simulations, we find temporal sequence correlations that constitute a signature of information transmission, weaker but of the same form as in a true replicator.
