The complete mitochondrial genome of Mauremys sinensis (Testudines: Geoemydidae) is sequenced in the study. It is a circular molecule of 16,458 bp in length, consisting of 37 genes typically found in other turtles. The AT content of the overall base composition of M. sinensis is 60.2%. The length of control region is 928 bp with 66.1% AT content. An insertion of additional adenine base was observed in location of 175th base of ND3 gene. Protein-coding genes begin with ATG as start codon except COI with GTG. ATP6, ATP8, COII, ND4, ND4L, and ND5 genes end with TAA as stop codon; ND1, ND2, and ND3 end with TAG; COI end with AGG; ND6 end with AGA; and COIII and Cyt b end with an incomplete stop codon (a single stop nucleotide T).
本研究对中华草龟（龟鳖目：地龟科）的完整线粒体基因组进行了测序。它是一个长度为16458 bp的环状分子，由其他龟类中常见的37个基因组成。中华草龟总体碱基组成的AT含量为60.2%。控制区长度为928 bp，AT含量为66.1%。在ND3基因第175个碱基位置观察到一个额外腺嘌呤碱基的插入。除COI以GTG作为起始密码子外，蛋白质编码基因均以ATG作为起始密码子。ATP6、ATP8、COII、ND4、ND4L和ND5基因以TAA作为终止密码子；ND1、ND2和ND3以TAG作为终止密码子；COI以AGG作为终止密码子；ND6以AGA作为终止密码子；COIII和Cyt b以不完整的终止密码子（单个终止核苷酸T）作为终止密码子。
