Symmetries by base substitutions in the genetic code predict 2' or 3' aminoacylation of tRNAs

This letter reports complete sets of two-fold symmetries between partitions of the universal genetic code. By substituting bases at each position of the codons according to a fixed rule, it happens that properties of the degeneracy pattern or of tRNA aminoacylation specificity are exchanged.

On the codon assignment of chain termination signals and the minimization of the effects of frameshift mutations

It has been suggested that the minimization of the probability for lethal mutations is a major constraint shaping the genetic code, with the finding that the genetic code is highly protective against transition mutations. Here, we show that recent data on polymerase-induced frameshifts provide a rationale for the codon assignment of chain termination signals (CTS).
