假如肿瘤是多克隆的，则是偶然因素引起两种异体的表达。

If the tumors were polyclonal, chance alone would dictate expression of both variants.

此外，由于我们无法搞懂的原因，克隆动物通常会自行流产，或者具有天生缺陷。“多莉”尽管看起来很健康，但是她很早就死了。

Besides, for reasons that aren't yet well understood, cloned animals often abort spontaneously or are born with defects; Dolly died very young, though she had seemed healthy.

我不想干预这么多，但我想我们应该在克隆人的问题上划定界限。

I didn't want to interfere with all that, but thought we should draw the line at human cloning.

The rest of this, this sort of beige part of the molecule here is called the polylinker part.

剩下这部分,这部分淡棕色的分子叫做多克隆位点

How we do that will be clear in a few minutes, but this polylinker as is described down here is a site where you can clone in genes.

马上你们就清楚这该怎么做了,这里所说的多克隆位点,就是你能把基因片段插进来的位点

We're going to have DNA that we would like to make lots of copies of, or we're going to have DNA that we would like to get expressed in a cell, and we're going to put it in this region that's called the polylinker.

我们将那些需要得到很多拷贝数的DNA,或者需要在细胞中表达的DNA,整合到这个叫做多克隆位点的区域中
