17、平 上进行设计和施工的,又叫做DNA重组技术 .（一）基因工程的基本工具1. “分子手术刀” 限制性核酸内切酶（限制酶）（ 1）来源：主要是从 原核生物 中分别纯化出来的.（ 2）功能：能够识别双链DNA分子的某种 特定 的核苷酸序列,并且使每一条链中特定 部位的两个核苷酸之间的磷酸二酯键 断开,因此具有 专一 性.（ 3）结果：经限制酶切割产生的DNA片段末端通常有两种形式：黏性末端 和平末端 .2. “分子缝合针” DNA连接酶(1) 两种 DNA连接酶（ E coliDNA 连接酶和 T4- DNA连接酶）的比较：相同点：都缝合磷酸二酯 键.区分： E coliDNA 连接酶来源于 T4

18、 噬菌体 ,只能将双链 DNA片段互补的 黏性末端 之间的磷酸二酯键连接起来.而T4DNA连接酶能缝合 两种末端 ,但连接平末端的之间的效率较 低.(2) 与 DNA聚合酶作用的异同:DNA 聚合酶只能将 单个核苷酸 加到已有的核苷酸片段的末端,形成磷酸二酯键.DNA连接酶是连接 两个 DNA片段 的末端,形成磷酸二酯键.3. “分子运输车” 载体（ 1）载体具备的条件：能在受体细胞中复制并稳固储存. 具有一至多个限制酶切点,供外源DNA片段插入 . 具有标记基因,供重组DNA的鉴定和挑选 .（ 2）最常用的载体是 质粒 , 它是一种 暴露的、结构简洁的、独立于细菌染色体之外,并具有自我复制才

19、能的双链环状DNA分子 .（ 3）其它载体：噬菌体的衍生物、动植物病毒 二 基因工程的基本操作程序第一步： 目的基因的猎取1. 目的基因是指：编码蛋白质的结构基因.2. 原核基因实行 直接分别 获得,真核基因是 人工合成 .人工合成目的基因的常用方法有反转录法 _和化学合成法 _.3. PCR 技术扩增目的基因（ 1）原理： DNA双链复制（ 2）过程：第一步：加热至 90 95DNA解链 .其次步：冷却到 5560, 引物结合到互补 DNA链.第三步：加热至 7075, 热稳固 DNA聚合酶从引物起始互补链的合成 .其次步： 基因表达载体的构建1. 目的：使目的基因在受体细胞中 稳固存在 ,
