It's a biological system that you've engineered from taking cells from one organism and cloning them and developing a whole other organism.
所谓生物系统的工程化,就是从一种生物体内中取出细胞并克隆,将它们培养成为另一个有机整体

But I do think that there are potential scientific and medical benefits for the use of cloning.
但是，我认为克隆技术的使用大大地推动了科学以及医学的发展。

We're going to talk about cloning next week, but why would cloning be an advantage in producing food?
下星期我们讨论克隆,为什么克隆技术在食品工业中具有优越性
-
Cloning? Well, I hate to land on one side of the debate or the other
克隆？我不希望在这种争论中选择某一个立场，
-
We're cloning a gene of interest to us by sort of hijacking that biological mechanism by putting our gene on this plasmid and so our gene gets copied many times, as the plasmid gets copied many times.
我们克隆感兴趣的基因的做法,这个生物机制有点像是绑架,我们把基因绑在质粒身上,随着质粒被多次地复制,我们的基因也一起被多次复制
-
DNA cloning, or any kind of cloning just means 'making copies of'.
NA克隆,或者任何一种克隆,本义就是"复制"

-
Here's another - that's a biological way of cloning it.
这里有另一种--,是一种克隆DNA的生物方法
-
So the process of cloning DNA is taking a few strands of DNA of a gene that you're interested in and making many copies of them, that's cloning,you like to make identical copies.
所以DNA克隆的过程,就是用你所感兴趣的,基因的一些DNA链,来得到更多它们的拷贝,这就是克隆,复制出相同的拷贝
-
What do you think of cloning?
你是怎样看待克隆的？
-
Let's assume that we have this plasmid cloning vector and we have some pieces of DNA that we would like to put into a plasmid that we would like to make copies of.
假设我们已经有了克隆质粒载体,也有了我们想要将之,整合到质粒上的某些DNA片段,同时也是我们所要复制的DNA片段
-
That's a way of cloning DNA.
