[ The sense strand is shown. Amino acids are in the single-letter code: the mtDNA genetic code differs from the "universal" code. ]

Interchanges of pyrimidine (c t) or purine (a g) bases are transitions (Ts)
Exchanges of pyrimidine for purine (pyr pur) bases are transversions (Tv)

Note numerous third-position polymorphisms in all sequences:
        note more complex pattern at last position ( a c t)

Note second-position transversion (t a) in the Mule Deer, resulting in an isoleucine asparagine  (I N)  substitution.

Note first-position purine transition (a g) in the Moose, resulting in an isoleucine valine (I V) substitution.

Note synonymous first-position pyrimidine transitions in leu (L) codons of Moose
