生物前RNA反应器中信息传输的出现

Emergence of information transmission in a prebiotic RNA reactor

B. Obermayer, H. Krammer, D. Braun, U. Gerland

摘要:

在从化学世界向生物世界过渡的过程中,人们对自我复制分子系统的出现知之甚少。我们研究了这样一个复制子的前体如何可能出现在水热RNA反应器中,该反应器从无偏单体流入和随机连接中积累了较长的序列。在反应器中,分子内和分子间的碱基配对局部地防止随机裂解。通过分析随机模拟,我们发现时间序列的相关性,构成了一个签名的信息传输,较弱,但在一个真正的复制相同的形式。

英文摘要:

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 inter-molecular basepairing 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.
