An extensive study of mutation and selection on the wobble nucleotide in tRNA anticodons in fungal mitochondrial genomes.

Abstract excerpt

Two alternative hypotheses aim to predict the wobble nucleotide of tRNA anticodons in mitochondrion. The codon-anticodon adaptation hypothesis predicts that the wobble nucleotide of tRNA anticodon should evolve toward maximizing the Watson-Crick base pairing with the most frequently used codon within each synonymous codon family. In contrast, the wobble versatility hypothesis argues that the nucleotide at the...
