Selective prebiotic formation of RNA pyrimidine and DNA purine nucleosides

Nature, Published online: 03 June 2020; doi:10.1038/s41586-020-2330-9

A prebiotic synthesis of the purine DNA nucleosides (deoxyadenosine and deoxyinosine) in which the pyrimidine RNA nucleosides (cytidine and uridine) persist has implications for the coexistence of DNA and RNA at the dawn of life.
