在人体基因组中,用“核心”顺序(coresequence)的串联重复子组成探针进行杂交,可同时检出许多具有高度多态性的小卫星(minisatellite)位点.用Southern吸印杂交方法可以得到DNA指纹图谱,这些“指纹”包含着多种高度可变的DNA片段,无论在体细胞还是生殖种系内,它们都很稳定.而且个体是完全特异的.我们的研究表明,这一技术能用于法医学鉴定.可以从残 In the human genome, a number of highly polymorphic minisatellite sites can be detected at the same time by hybridizing with “coresequence” tandem repeats to make probes. Southern blotting hybridization DNA fingerprinting is available and these “fingerprints” contain a variety of highly variable DNA fragments that are stable both in somatic and germline lines and that the individual is completely specific. Our research shows that, This technique can be used for forensic identification
