1996年，世界第一例从成年动物细胞克隆出的哺乳动物绵羊多利诞生 在培育多莉羊的过程中，科学家采用了体细胞克隆技术。也就是说，从一只成年绵羊身上提取体细胞，然后把这个体细胞的细胞核注入另一只绵羊的卵细胞之中，而这个卵细胞已经抽去了细胞核，最终新合成的卵细胞在第三只绵羊的子宫内发育形成了多莉羊。从理论上而言，多莉继承了提供体细胞的那只绵羊的遗传特征。培育多莉羊的技术，已经成为如今培育体细胞克隆动物的标准过程。 Cloning: Where is it leading us?CloningUnit 2Reading :Skimming（略读）:match the main idea with each paragraph（段落大意连连看）A.Two major uses and the
