Biotechnology applications Why take this course? 您的描述对于理解PCR、DNA分子序列和遗传指纹(DNA鉴定)的过程是非常全面的。让我们稍微梳理一下这些信息,并补充一些细节。 PCR(聚合酶链式反应): PCR是一种实验室方法,用于在少量DNA模板上快速和可靠地复制大量DNA。 这个过程包括三个步骤:分离、扩增和结合(denature、anneal、extend)。 PCR可以从一些几乎不足以检测的起始材料中生成数百千竖米到数万英里量的DNA副本。 这是许多实验室工作坊和临床测试中不可或缺的技术,包括遗传鉴定、病毒分子检测和基因工程。 DNA序列: DNA序列是沿着DNA双链的顺序,指的是核苷酸A、T、C和G在DNA中的具体排列。 Sanger等人在1970年代发明了一种可以详细阅读DNA序列的方法,这是当时的一项重大突破。 这个过程涉及到四个反应,每个都带有一个不同的无机基(dATP、dTTP、dCTP或dGTP)和一个相应的荧光寿命标记的ddNTP。 随着电泳,每种无机基与其相对应的染色体段结合,形成了一系列带有不同荧光颜色的带子。 通过比较这些带子的模式,科学家可以确定DNA的确切序列。 自动化的染色质酶链式反应(dye-terminator sequencing): 自动化分子序列技术是对传统Sanger方法的改进,它更快,同时提高通量和效率。 DNA鉫(DNA fingerprinting): DNA鉫(或DNA分型)是一套基于个体遗传物质的特点集合。 每个有性染色体的这些特征是由两个父母和一个母亲交叉产生的随机方式导致的。…
