In animals, mitochondrial DNA is generally a 15-22 kb circular genome containing 37 genes: 13 protein-coding genes, two rRNA genes, and 22 tRNA genes, as well as a control region. All 37 genes are arranged in the same relative order almost in all vertebrate species from teleost fishes to eutherian mammals. In recent years, mtDNA has been widely used as a useful marker system in numerous phylogenetic analyses in vertebrate relationships.
