Fig. 1.

Multiple sequence alignment of the “WANCY region” in eight different primates. The analysis showing very high levels of sequence similarity throughout. The proper annotation of each tRNA gene as determined by manual folding of potential secondary structures is shown in black above the alignment. Nucleotides shown in red are those predicted to be paired in the amino-acyl acceptor arm of the mature tRNA. The annotations of these genes as they appear in the GenBank records is shown below each sequence with green representing conformity to the annotation inferred to be correct, brown representing errors in designating the endpoints of the genes, and red representing errors in gene orientation
