从古代的“滴血认亲”到现如今的分子生物学检测技术,亲子鉴定的准确率逐步升高,重要性要逐步提高;而DNA指纹技术的产生,成为了分子生物学技术当中的新方法,它可以从分子水平对不同种类生物之间或者同种生物之间差异进行区别鉴定,本文作者主要阐述了DNA分子技术以及它在亲子鉴定当中的应用及意义。 From the ancient “blood and identify their relatives ” until now the molecular biology detection technology, the accuracy of paternity testing gradually increased, the importance should be gradually increased; and DNA fingerprinting technology has become the molecular biology technology The new method, which can distinguish different species of organisms or between species of the same species at the molecular level, is distinguished from each other. The author mainly expounds the DNA molecular technology and its application and significance in paternity testing.
