The complete mitochondrial DNA sequence of Mang Mountain Pit Viper (Zhaoermia mangshanensis) was determined by using the polymerase chain reaction (PCR) method in this study. The entire length of the complete mitochondrial genome is 17,628 base pairs (bp). Just like most snakes, besides 2 control regions (CRI and CRII), the nucleotide contains 37 coding genes, exactly, 13 protein-coding genes, 22 tRNA genes and 2 rRNA genes. The gene content, organization and arrangement of the new mtDNA are highly similar to those of other vipers reported so far. It confirms again to the order and rearrangement of two tRNA genes (tRNA-Pro and tRNA-LeuUUR), which differs from the typical organization found for many vertebrates. Duplication of the control region and translocation of the tRNALeu(UUR) gene are two notable features of the snake mt genome (except the scolecophidians: blindsnakes and threadsnakes). |
