Advanced #1663 DNA鉴定

    DNA鉴定绝对是20世纪以来，法医学界的最大发现之一。到目前为止，DNA是能辨识、区别人的最有效的鉴定手段，对法官来说，DNA鉴定比笔迹、指纹甚至目击证人的可信性都要大。 案件侦破过程中，警方除了能在现场留下的血迹中提取到DNA外，还可以在如毛发，嚼过的口香糖，烟头等等不易被察觉的样本中找到有关犯罪嫌疑人的DNA信息。

     DNA不但帮助警方将许多罪犯绳之以法，也能让许多冤假错案得以昭雪。DNA鉴定之父自己可能也没有料到，他在 1953年偶然的发现 已经成为了当今司法界最重要的举证方法之一。虽然DNA所向披靡，但它的保存却必须非常小心，一旦受到污染将彻底失去价值。

    

DNA paternity test is definitely the biggest discovery of the medical community in 21st century. So far, DNA paternity test is the most effective way to distinguish people. For judges, there is nothing more convincing such as handwriting, fingerprint or witness than it. During the investigation, apart from the DNA extracted from the blood collected on the spot by policemen, it also can be found in hair, gum that has been chewed, cigarette ends and other samples which may not be obvious.

DNA Paternity Test not only helps policemen bring criminals to justice, but also right the wrong. The founder of DNA paternity test may never expect that his accidental discovery would become one of the most important proofs in today's judicial circle. Despite its great advantages, DNA paternity test must be preserved carefully. Once contaminated, it would lose its value.
