Figure 2From: Modelling evolution on design-by-contract predicts an origin of Life through an abiotic double-stranded RNA worldAbiotic generation of dsRNA as a primitive information carrier. Based on the availability of oligoribonucleotides, the first step in the generation of dsRNA is initiated when small oligonucleotides stick together to form an interrupted double-stranded chain of RNA. Ligation of the oligonucleotides by a slow abiotic process leads to a tight dsRNA chain.Back to article page
