Objective: To sequence and analyze the complete mitochondrial DNA of Chinese moccasin.
Methods: The circular 17 541 bp sequence of mitochondrial DNA (mtDNA) of Chinese moccasin was determined by Ex-Taq PCR, TA-cloning and primer-walking methods.
Results: This mitogenome contained 37 coding genes (including 22 tRNA, 2 rRNA and 13 protein-coding genes) and two control regions (CR and psiCR). The gene content and arrangement of Chinese moccasin mtDNA was similar to those of other vipers reported so far.
Conclusion: The characteristics of the replication origin and the tRNA arrangement of snake mitochondrial genomes can be used for identification of medicinal snakes.
