title: Formation of P1, P2-dinucleoside 5'-pyrophosphates under potentially prebiological conditions.
abstract: Organic pyrophosphates such as UppA and NAD are formed when a solution containing a nucleotide, a nucleoside 5'-polyphosphate, Mg2+ and imidazole are allowed to dry out. We suggest that this synthesis may have occured concurrently with oligonucleotide formation.
