PhageDNA
IntroductionThe phage lysate from the plate contains bacterial DNA and RNA, as well as phage DNA encased in the phage coat. The following procedure, digests bacterial RNA and DNA, precipitates the phage particles, then removes the phage coat with organic extraction. Finally, the DNA is purified by precipitation with alcohol and visualized by gel electrophoresis.Protocol 1. Add RNase A and DNase I, each to a fina......阅读全文

烈性噬菌体（virulent－phage）和温和噬菌体（temperate－phage）
噬菌体(bacteriaphage or phage)是病毒的一类，结构很简单，基本上由一个蛋白质外壳包裹着一些核酸组成的。噬菌体的多样性来自于组成其外壳的蛋白质的种类，以及其染色体的类型和结构的不同。（一）烈性噬菌体（ virulent phage）遗传学上应用最广泛的烈性噬菌体是大肠杆菌（ E.

其基本原理是：用一个在种源上相近的基因组将靶基因组中所有共同的基因掩盖起来,而只暴露出特异的基因,在整个反应中只有特异基因能被扩增。其操作程序为:(1)用同一限制性内切酶(一般用Bam HI,Bgl II或Hind III)同时处理靶基因组和掩盖基因组DNA，其中掩盖基因组DNA的量至少要2
