克隆哺乳动物

欧洲或许培育了全球第一只克隆哺乳动物——多利羊（Dolly），但是欧盟于今年9月开始禁止克隆家畜。

Europe might have produced the first cloned mammal , Dolly the sheep , but in September the EU banned the cloning of farm animals .

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 .

他说，甚至第一只克隆哺乳动物，即著名的克隆羊多莉，也患有肥胖症和脑异常。

He said that even Dolly , the famous sheep that was the first mammal to be cloned , suffered from obesity and brain abnormalities .

整体水平：移植瘤生长抑制试验。其次，通过两步PCR方法按照人的密码子偏爱性合成K5蛋白的DNA序列，克隆至哺乳动物细胞表达载体pDV，并对其生物学活性进行初步研究。

The full DNA sequences of K5 protein were synthesized by two steps PCR , and PCR products were cloned into mammal expression plasmid pDV . Its activity of anti-tumor was studied in mouse tumor model .

1997年2月，我和我的同事们宣布了第一头从成体细胞克隆出的哺乳动物－－多利羊的出生。

In February 1997 , my colleagues and 1 announced the arrival of Dolly the sheep , the first mammal cloned from an adult cell .

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 .

多利，世界上第一只克隆羊，是第一只成功由体细胞克隆而成哺乳动物。

Dolly , a ewe , was the first mammal to have been successfully cloned from an adult cell .
