Abstract
The complete mitochondrial genome sequence of Nematalosa nasus was determined in this paper. The entire sequence was 16,674 bp in length and the overall base compositions were 26.5% of A, 28.4% of C, 25.4% of T and 19.7% of G. The mitogenome contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and two non-coding regions (the control region and the light strand replication origin). Gene arrangement was similar to that observed in most other vertebrates. Except for the ND6 genes and eight tRNA genes, all other genes were encoded on the heavy strand. Within the control region, the extended termination associated sequence was identified, as well as four central conserved sequence blocks (CSB-F, CSB-E, CSB-D and CSB-C) and three conserved sequence blocks (CSB-1, CSB-2 and CSB-3).
