Xenopus borealis mitochondrial genome. The complete mitochondrial genome of Xenopus borealis (17,474 bp, drawn to scale) All 13 protein coding genes are shown as open arrows, 2 ribosomal RNAs as shaded arrows and 22 tRNAs as arrowed lines. Each tRNA is shown by its single letter amino acid code. The two leucine and two serine tRNAs are differentiated by their respective anti-codons. The direction of transcription is indicated by the arrows. Also shown is the non-coding D-loop (control region, black) and the position of the primers (LongF1/R2 and LongF2/R1) used to generate the two long-PCR amplicons, which were pooled and sequenced using 454 technology.
