Yockey * 1507 Balmoral Drive, Bel Air, MD 21014-5638, USA Received 22 December 1998; accepted 8 May 1999 A b s t r a c t The genetic information system is segregated, linear and digital. It is astonishing that the technology of information theory and coding theory has been in place in biology for at least 3.850 billion years (Mojzsis, S.J., Kishnamurthy, Arrhenius, G., 1998. Before RNA and after: geological and geochemical constraints on molecular evolution 1-47. In: Gesteland, R.F. (Ed.), The RNA World: The Nature of Modern RNA Suggests a Prebiotic RNA, second ed. Cold Spring Harbor Laboratory Press, Boca Raton, FL). The genetic code performs a mapping between the sequences of the four nucleotides in mRNA to the sequences of the 20 amino acids in protein. It is highly relevant to the origin of life that the genetic code is constructed to confront and solve the problems of communication and recording by the same principles found both in
