Abstract
To set in motion the evolutionary organization required self-reproducing information storage admittedly assumed by the “RNA world”. However, because of the scarce prebiotic availability of ribose, this role of RNA would have been preceded by sugarless prenucleic polymers of a “pre-RNA world” (Picirilli, 1995; Brack, 1998).
