Some consequences of the RNA world hypothesis

Orgel, Leslie E.·2003·Origins of life and evolution of the biosphere

Abstract

It is now generally accepted that our familiar biological world was preceded by an RNA world in which ribosome-catalyzed, nucleic-acid coded protein synthesis played no part. If the RNA world was the first biological world there is little that one can learn from biochemistry about prebiotic chemistry, except that the formation and polymerization of nucleotides were once prebiotic processes. If the RNA world was not the first biological world, the above conclusion may not be justified, and one can speculate that the monomers of earlier genetic polymers might be recognizable as important biochemicals. This suggests that the construction of replicating polymers from simple, not necessarily standard, aminoacids should be explored.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
