These patterns do not, however, give an individual fingerprint, they are able to determine whether two DNA samples are from the same person, related people, or non-related people. DNA Fingerprinting using VNTRs On some human chromosomes, a short sequence of DNA has been repeated a number of...
DNA指纹技术 (一) DNA指纹技术(DNAFingerprinting)--用限制性内切酶消化基因组DNA,并用特异性核酸探针杂交,取得不同大小的DNA片段的区带图谱,该图谱具有高度的个体特异性,类似于人的指纹。类型限制性片段长度多态性(restrictionfragmentlengthpolymorphism,RFLP)数目可变的串联重复多态性(Variblenumberoftandemrepeats,VNTR)...

(散在重复DNA) DNA fingerprinting depends on differences in length of minisatellite or microsatellite DNA 基因组DNA中含有高变区,是一系列可变数目串连重复序列,具有高度多态性 ,不同高变区的重复单位内有一段序列是近似的,被称为核心序列,以此做为探针对DNA分子进行限制性片断长度多态性分析,可检测出许多高变...
These patterns are like fingerprints – DNA fingerprints 这些模式就像指纹 - DNA指纹 ; RFLP = Restriction Fragment Length Polymorphism 限制性片段长度多态性 DNA指纹分析的是基因型特征 DNA fingerprinting (DNA typing) is used to characterize biological samples e.g.: In legal proceedings to identify ...

DNA Except for identical twins, no two people on earth have the same DNA. Since the 1980s, DNA has been used to solve crimes, identify victims, and establish paternity. It is especially useful in large-scale disasters, like plane crashes, hurricanes and tsunamis to identify victims. ...
