The Hypercycle theory explains this, it says that Nucleotids formed because of organic molecules in the primordial atmosphere combined to form small RNA molecules which catalysed, like ribozymes, the formation of more RNA. So I guess it was the RNA because it can function as an enzyme on top of stor...
