On the origin of the transfer RNA molecule

Giulio, Massimo Di·1992·Journal of Theoretical Biology

Abstract

Data and arguments are given in favour of the hypothesis that the primitive tRNA molecule may have originated from a direct duplication event involving one of the two halves of the tRNA molecule. It seems that a molecule capable of assuming a hairpin structure was involved as a precursor in this duplication. The two halves of the present tRNAs could, therefore, be considered as paralogous.

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.
