In the prebiotic era, on the surface of the early Earth, UV light could have played a major role in the selection of the building blocks of life via a balance between synthetic and destructive pathways. As nucleic acid monomers assembled into polymers, their survival and facility for non-enzymatic replication hinged on their photostability and the ability for self-repair of lesions, e. g., by UV-induced charge transfer. Such photoprocesses are known to be sequence-dependent and could have led to an additional prebiotic selection of the genetic sequence pools available to the earliest life forms.

The oligomerisation proceeded at a pH range of 7–12, at temperatures between 40–80 °C and was marginally enhanced by K<sup>+</sup> ions. Among the canonical ribonucleotides, cGMP oligomerised most efficiently. Quantification was performed using HPLC coupled to ESI-TOF by fitting the isotope distribution to the mass spectra. Our study suggests a oligomerisation mechanism where cGMP aids the incorporation of the relatively unreactive nucleotides C, A and U.
