Figure 3.

Phylogenetic tree of glycine tRNA gene sequences from bacteria, archaea and eukaryote cytoplasm. The phylogenetic relaxed neighbour joining tree was constructed by using 466 glycine tRNA gene sequences from eubacteria, archaea and eukaryote cytoplasm, taken from [13]. Branches including tRNA gene sequences not containing an anticodon loop CCA sequence are shown in colour, and indicated by the particular labels (with number of sequences in brackets).
