Autocatalytic synthesis of a tetranucleotide analogue

Zielinski, Wojciech S., Orgel, Leslie E.·1987·Nature

Abstract

As an approach to the study of the kind of chemical process that might have contributed to the origin of life, attempts have been made to develop purely chemical systems in which oligonucleotides self-replicate. Although performed oligonucleotides have been shown to facilitate the formation of their complements from activated mononucleotides, only a restricted range of oligomers are efficient templates and it will clearly be difficult to find a pair of complementary oligomers each of which will facilitate the formation of the other. Many of the difficulties facing the development of a self-replicating system could be overcome by using a pair of complementary substrate molecules that condense together more easily than ribonucleotides. It would also be helpful if each substrate molecule contained equal numbers of purine and pyrimidine bases as, otherwise, there is a tendency for purines to be overrepresented in the products. We have therefore explored the chemistry of 3'-amino-3'-deoxynucleotides and their dimers. We report here that the tetranucleoside triphosphoramidate GNHpCNHpGNHpCN3 acts as a template to catalyse the condensation of GNHpCNH2 and pGNHpCN3, forming further molecules of the template. The system is therefore autocatalytic, and in accordance with elementary theory the amount of product made increases with the square root of the template concentration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
