Abstract
The complete mitochondrial genome of Lithobates catesbeianus (Anura: Ranidae) is sequenced to analyze the gene arrangement. It is a circular molecule of 18,241 bp in length including 37 genes typically found in other frogs. The AT content of the overall base composition of L. catesbeianus is 59.9%. The length of control region is 2783 bp with 66.0% AT content. Protein-coding genes begin with ATG as start codon except except ND1 and ATP6 began with ATA, COI and ND4L with GTG, and ND2 with ATT. COI end with AGG as stop codon, COII and ND6 end with AGA, ND2 end with TAG, ATP8. ND4L. ND5 and Cytb end with TAA, and the other five PCGs end with a incomplete stop codon (a single stop nucleotide T).
