producing the genetic twin of another organism.
The three types of cloning technologies are:
(1) recombinant DNA technology or DNA cloning（基因重组克隆技术） (2) reproductive cloning（再生克隆技术） (3) therapeutic cloning（干细胞疗法克隆技术）
因此, 人们开始探索用人工的方法来生产高等
动物克隆。这样, 克隆一词就开始被用作动词, 指人工培育克隆动物这一动作。目前, 生产哺乳动物克隆的方法主要有胚胎分割和细胞核移植两种。克隆羊“多莉”, 以及其后各国科学家培育的各种克隆动物, 采用的都是细胞核移植技术。
所谓细胞核移植，是指将不同发育时期的胚胎或成体动物的细胞核，经显微手术和细胞融合方法
