DNA Testing
DNA testing is a powerful tool for identification and has many practical applications. / Molecule DNA carries our genetic code and determines our characteristics. / 99.9% of the DNA from two people will be identical. / The 0.1% of DNA code sequences that vary individually are called genetic markers. / The key to DNA testing is to find the genetic markers / that will identify the important similarities or differences between people. / The accuracy of DNA tests has big implications. / They are sometimes the only evidence to prove a suspect was guilty, / or free someone wrongly convicted. /
It’s easy to tell if DNA from two biological samples doesn’t match. / But a match doesn’t ensure that the two samples come from the same person. / A small chance exists that two different people’s genetic markers could be the same, / especially if they are related. / However, the chance that two unrelated people have identical profiles / is less than one in one billion. /
解析
DNA测试
DNA测试是识别身份的一个有力工具。两个人的DNA当中有99.9%是一样的。剩下那0.1%的DNA编码序列叫做基因标记。DNA测试的关键在于找到基因标记,以确定人与人之间重要的共同性或差异性。
