Complete mitochondrial DNA genome of Onychostoma sima (Cypriniformes: Cyprinidae)

Abstract

In this study, we sequenced the complete mitochondrial genome of Onychostoma sima (Cypriniformes, Cyprinidae). This mitochondrial genome, consisting of 16,601 base pairs (bp), encoded 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a noncoding control region as those found in other vertebrates, with the gene synteny identical to that of typical vertebrates. Control region (D-Loop), of 934 bp lengths long, is located between tRNAPro and tRNAPhe. The overall base composition of the heavy strand shows 24.30% of T, 28.28% of C, 31.31% of A and 16.11% of G, with a slight AT bias of 55.61%.
