The complete mitochondrial genome of bean goose (Anser fabalis) and implications for anseriformes taxonomy.
Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in a variety of evolutionary studies. In this study, we determined the complete mtDNA of Bean goose (Anser fabalis), which is 16,688 bp long and contains 13 protein-coding genes, 2 rRNAs,...

Mitochondrial DNA plays an important role in living organisms, and has been used as a powerful molecular marker in a variety of evolutionary studies.

All tRNAs could be folded into canonical cloverleaf secondary structures except for tRNA(Ser)(AGY) and tRNA(Leu)(CUN), which are missing the dihydrouridine (DHU) arm.
