• dna聚合酶i    由RNA酶H降解RNA引物并由DNA聚合酶I将缺口补齐，再由DNA连接酶将每两个冈崎片段连在一起形成大分子DNA.。 但是DNA聚合酶I催化合成DNA时，需要自由3’?OH作为引物，最后余下子链的5’无法填补，于是染色体就短了一点。 以后随链复制为例，当RNA引物被切除后，冈崎片段之间是由DNA聚合酶I催化合成的DNA填补之，然后再由DNA连接酶将它们连接成一条完整的链。 ...
• dna聚合酶iii    引发体似火车头一样在后随链分叉的方向前进，并在模板上断断续续的引发生成滞后链的引物RNA短链，再由DNA聚合酶III作用合成DNA，直至遇到下一个引物或冈崎片段为止。
• dna聚合酶α    ，如：DNA聚合酶α、DNA引物酶、DNA拓扑异构酶II等。 真核生物中有DNA聚合酶α、β、γ、δ、ε五种，其中δ为主要的聚合酶，γ存在于线粒体中。 主要的酶(占总量的80-90%)是DNA聚合酶α，分子量为300KD，含有4个或5个亚基，主要负责染色体DNA的复制。 （2）在电镜下观察到双螺旋DNA聚合酶α也同样具有两个活性部位，推测双螺旋复制也是同时复制的。 拉米夫定...
• dna聚合酶γ    1.H链首先合成：在复制起点处以L链为模板，合成─RNA引物，然后由DNA聚合酶γ催化合成一个500-600bp长的H链片段。
• dna聚合酶δ    外切酶活性，称为DNA聚合酶δ。 能与DNA聚合酶δ、聚合酶ε、复制因子C结合，并使DNA在其形成的环中滑行，使前导链连续合成。 PCNA是一种分子量为36KD的蛋白质，在细胞核内合成，并存在于细胞核内，为DNA聚合酶δ的辅助蛋白。 同时探讨编码DNA聚合酶δ催化亚基的pold1基因细胞周期依赖性表达，确定pold1基因在细胞增殖调控中的作用以及与细胞癌变的关系。 ②Kip...
• rna依赖性dna聚合酶    RNA依赖性DNA聚合酶RNA dependentDNA polymerase为依赖于RNA合成DNA的酶，亦称逆转录酶（反向转录酶，reverse transcriptase）。 但目前认为，端粒酶为RNA依赖性DNA聚合酶，端粒酶的亚单位工作是以RNA为模板合成端粒DNA片段。
