摘要
基因组中由寡核苷酸串联、重复排列的DNA序列,构成数量可变的串联重复序列,其中,微卫星DNA又称为短串联重复停列.是一种可遗传的不稳定的且具有高度多态性的短核苷酸重复序列,具有种类多,分布广,高度多态性等特点,这种多态性标志已广泛用于遗传病及亲子鉴定等.
DNA short tandem repeat in gene group constitutes variable number of tandem repeat, microsatellite DNA is called short tandem repeat. It is hereditary, unstable anti high-polymorphism, its marker as high- polymorphism has been widely applied in many fields of genetic disease research and paternity testing.
