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).

摘要

对牛蛙(无尾目:蛙科)的完整线粒体基因组进行测序以分析基因排列。它是一个长度为18241 bp的环状分子,包含其他蛙类中常见的37个基因。牛蛙总体碱基组成的AT含量为59.9%。控制区长度为2783 bp,AT含量为66.0%。蛋白质编码基因除了ND1和ATP6以ATA起始、COI和ND4L以GTG起始、ND2以ATT起始外,均以ATG作为起始密码子。COI以AGG作为终止密码子,COII和ND6以AGA作为终止密码子,ND2以TAG作为终止密码子,ATP8、ND4L、ND5和Cytb以TAA作为终止密码子,其他五个PCG以不完全终止密码子(单个终止核苷酸T)结束。
