A logical-evolutionary analysis is conducted to clarify whether or not pathways of type Glu-tRNAGln \rightarrow Gln-tRNAGln are molecular fossils of the mechanism that gave rise to the evolutionary organization of the genetic code. The result of this analysis is that these pathways are most likely a manifestation of this mechanism. This provides strong evidence in favor of the coevolution theory of genetic code origin, as this theory is based on the amino acid biosynthetic transformation taking… CONTINUE READING
