Abstract
The complete nucleotide of mitochondrial DNA of a skate Raja rhina was investigated for the first time. It is 16, 910 bp in length containing 2 rRNA, 22 tRNA and 13 protein coding genes generally found in other vertebrates. The gene configuration and structure of the genome is similar to those of other Rajidae species. The genome was composed of 30.1% A, 27.2% C, 28.5% T, and 14.2% G showing high A+T content. The G is the least used base and markedly lower at the third codon position (5.4%). Twelve of the 13 mitochondrial protein-coding genes use ATG as their start codon while the COX1 gene starts with GTG. As for stop codon ND4 gene has incomplete stop codon TA, while the COX2 and ND3 genes use AGA and TAG respectively. The control region spans 1,251 bp in length. This data provide the necessary background for the application of the mitogenome in studying phylogenetic relationships within Rajidae, as well as population genomics within R. rhina.figuration and structure of the genome is similar to those of other Rajidae species.
