(Naitoh, 2008) ATP run off from RNA is something like the joker in the card-game of old maid. The other redundant uridine triphosphate (UTP) became polysaccharide-generator.
Possible answers were given also for the questions why two types of nitrogenous bases, large purine and small pyrimidine, are used for nucleic acids and also why only twenty types of amino-acids are employed for proteins.

& Molecular Evolution Andrew J, Pratt*, Vladimir Golovko, Henry Toombs-Ruane Department of Chemistry, University of Canterbury, New Zealand In accordance with Mike Russell’s model for the origin of life at alkaline hydrothermal vent systems (Martin and Russell, 2003) iron-sulfur mineral systems mediate a wide variety of processes that are required for the origin of metabolism and hence life on earth: they provide a continuous input of redox energy; and catalyse a range of transformations that mimic extant FeS-dependent processes of anaerobic metabolism including carbon (Huber and Wächtershäuser, 1997) and nitrogen (Dörr et al., 2003) fixation reactions. Furthermore, iron mineral precipitates catalyse biomimetic phosphoryl-transfer processes, including the generation and accumulation of polyphosphates (de Zwart et al., 2004).
