Dolly the sheep was the first cloned mammal, but scientists have struggled to reproduce even the early steps in people.

多利羊是首个科隆哺乳动物，但科学家一直努力再造人类繁殖的早期阶段。

2018 will also be remembered as the year that genetic engineering made significant advances from the techniques modest beginning with Dolly the sheep in 1997.

2018 年也将被铭记为基因工程从 1997 年多莉羊开始的技术取得重大进展的一年。

So other examples in the world of DNA the cloning of Dolly the sheep was a world-first and also the astronauts landing on the Moon in 1969.

因此，在 DNA 世界中的其他例子中，多莉羊的克隆是世界第一，1969 年宇航员登陆月球也是如此。

Yeah. So other examples in the world of DNA, the cloning of Dolly the sheep was a world first, and also the astronauts landing on the Moon in 1969. It's a world first.

是的。在 DNA 领域的其他例子，克隆绵羊多莉是世界首例，还有 1969 年宇航员登陆月球也是世界首例。
