克隆绵羊

克隆绵羊&多莉（DOLLY）的研究进展

Research Advances on Cloned Sheep - Dolly

自1996年克隆绵羊多莉（Dolly）诞生以来，研究人员已经克隆出大约20个不同物种，包括兔子、山羊、奶牛和猫。

Since the birth of Dolly the sheep in 1996 , researchers have cloned about 20 different species , including rabbits , goats , cows and cats .

体细胞克隆绵羊“多莉”（dolly）的诞生，表明成年哺乳动物体细胞具有基因组的全能性。

The birth of cloned sheep " dolly " produced by nuclear transfer from a somatic cell manifests that the somatic cell is of genomic totipotency in mammals .

PPL（克隆绵羊多莉的那家公司）已经提出一项专利申请，其中包括将克隆的人类胚胎作为知识产品。

PPL , the company that cloned the sheep named Dolly has applied for a patent that includes cloned human embryos as intellectual property .

结果如下：根据牛的基因序列和绵羊ESTs数据库，设计特异性扩增引物，克隆绵羊CAST、MC4R和BTG1基因的部分序列，推导其相应的氨基酸序列，并与其它物种进行同源性分析。

The results were as follows : Primers were designed based on cattle sequences and the contigs from ESTs database of sheep , the partial fragments of three genes were isolated , and the corresponding protein sequences were deduced and compared with some of other species .

北京对此既羡慕又谨慎，因为在1996年，首只克隆哺乳动物，绵羊多莉（Dolly），在苏格兰出生。

Beijing has watched with both envy and caution since the first cloned mammal , Dolly , a sheep , was born in Scotland in 1996 .

米克先生持有一张专营许可证，可使用一种专项技术（1996年曾用其克隆出了绵羊多莉）克隆曾经或可能的马球赛马。

Mr Meeker holds an exclusive licence to use a specific technique ( the one used to create Dolly the sheep in 1996 ) to clone horses that have been , or might be , used for polo .

克隆技术与社会伦理&对克隆绵羊的科学哲学与科学伦理学的反思

Cloning and Social Ethics

这项技术带来了世界上首只克隆动物——青蛙，进而又出现了首只克隆哺乳动物——绵羊多莉。

It led to the first cloned animal-a frog-and to the first cloned mammal , Dolly the sheep .

一些克隆动物已成功繁殖，包括全球第一例克隆哺乳动物，绵羊多利，她已生下数只健康的小羊。

Some cloned animals have been successfully bred , including Dolly the sheep , the world 's first cloned mammal , which has given birth to several healthy lambs .
