众所周知,每个人都有其独特的指纹特征,人们可以通过指纹来识别不同的人。那么,什么是 DNA指纹呢?实际上,从“DNA”和“指纹”两个词的表面上就可以猜出个大概意思了,就是把 DNA 作为像指纹那样的独特特征来识别不同的人。英国科学家亚历克·杰夫里斯,在1985年研究基因变异时偶然发现基因上存在着一些微小的结构,而这些结构足以区别不同的个体。因此,他想到是否可以利用这种结构上的差异来区分不同的人,并绘制出了世界上第一幅 DNA 指纹。他通过分子化学的方式将生物的遗传物质 DNA
As we all know, everyone has its own unique fingerprint feature, people can identify different people by fingerprints. So, what is DNA fingerprinting? In fact, one might guess the surface of both the words “DNA” and “fingerprinting,” as DNA is identified as a unique feature like a fingerprint different people. British scientist Alec Ge Jeffris, in 1985 when he studied genetic variation, stumbled upon the existence of tiny structural genes that were enough to distinguish different individuals. So he wondered if this structural difference could be used to distinguish between different people and to draw the world’s first DNA fingerprint.
