Mechanistic possibilities in prebiotic thiophosphate chemistry
Journal of Molecular Evolution, 1978Two types of reactivities of thiophosphates have been demonstrated: one being nucleophilic displacement by the P-S moiety of nucleoside phosphorothioates and the other, phosphorylation via P-S cleavage as the driving force. We have designed a system where both displacement on carbon and P-S cleavage are possible.

The importance of prebiotic chemistry in the RNA World
Current Opinion in Chemical Biology, 2004In vitro selection experiments have clearly demonstrated that RNA can perform many of the functions necessary to support an RNA world. Moreover, it appears that novel functions could have readily evolved from existing functional RNA molecules. Therefore, diverse molecular ecosystems could potentially have arisen from an initial, small population of ...

Recent progress in the prebiotic chemistry of HCN
Origins of Life, 1984This article reports some recent results on the mechanisms of synthesis of biologically important molecules in oligomerizing solutions of HCN. It will also attempt to summarize, as completely as possible, our present state of knowledge concerning the range of products obtained under a variety of conditions in this reaction system.

Prebiotic Chemistry on the Primitive Earth
2006Abstract The origin of life remains one of the humankind’s last great unanswered questions, as well as one of the most experimentally challenging research areas. It also raises fundamental cultural issues that fuel at times divisive debate.
