褐家鼠又叫大家鼠、沟鼠,俗称大老鼠、大耗子.属啮齿目（Rodentia）鼠科（Muridae）.分布于全国各地,凡是有人居住的地方,都有该鼠的存在.最常见的是黑鼠（R.rattus）与褐鼠（R.norvegicus）.由于数量多,危害大,因此是广大农村和城镇最主要的害鼠之一.褐家鼠是重要的生物医学模型动物,广泛应用于医学、生物学、遗传学等各个领域的研究.本实验对中国东北漠河地区的4只褐家鼠的线粒体DNA进行测序,旨在研究漠河褐家鼠线粒体控制区的DNA序列多样性.采用基因组DNA提取和PCR测序的方法,对控制区进行扩增和序列测定,根据测序结果用DNAstar和Mega 5.2分析其遗传多样性,实验结果如下：四只漠河褐家鼠的基因组大小均为 bp,其控制区序列中T、C、A、G的平均含量分别为:T:%、C:%、A:%、G:%,不同个体间碱基组成几乎无差别.而将实验序列数据与江苏如皋褐家鼠样品的控制区序列数据进行对比并构建系统进化树后发现,不同地区的褐家鼠其线粒体控制区序列是存在一定遗传差异的.

Rattus norvegicus is also called the rat, Rattus norvegicus ,commonly known as mices , rats, belongs to Rodentia (Rodentia) rats (Muridae) distributed in all parts of the country where there is a place for people to live in .Common black rats (R. rattus), and brown rats (R. norvegicus). as the number of multi hazard sovast rural and urban rodents Rattus norvegicus the biomedical model animal is widely used in various fields of medicine, biology, genetics research of Northeast China's Mohe County region of mitochondrial DNA were sequenced 4 RattusRattus norvegicus mtDNA control region of Mohe County concentrates on DNA sequence diversity by genomic DNA extraction and PCR sequencing method to control areas were amplified and sequenced according to DNAstar and Mega 5.2analysis of the genetic diversity and sequencing, the knot: four Mohe CountyRattus norvegicus genome size BP the control region sequences T, C, A, G average content respectively: T:%, C:%, A:%, G:%, with almost no differencebetween base composition and experimental sequence data and Jiangsu GaoRattus norvegicus sample control sequence data comparison and phylogenetic tree was constructed with the discovery of Rattus norvegicus mtDNA control region sequences genetic differences
