When I talked about mitosis, I talked about cells making perfect copies of each other, so each parent cell becoming two daughter cells that are the same.

我讲有丝分裂的时候,谈到过细胞能够完美的复制自己,母细胞分裂成为,两个完全一样的子细胞

If I want to clone a gene from a human, if I want to clone the gene for human isulin, mean make many copies of the gene that's responsible for making insulin, I need to know whether there are introns there or not.

如果我想要从一个人类个体克隆基因,如果我想要克隆人类胰岛素基因,亦即我要把负责生成胰岛素的基因,复制许多个副本,我就得要知道哪些是内含子,哪些不是

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

So, when the right signal is received, the right T-cell finds your host cell with a foreign virus in it, the first thing that happens is that this T-cell becomes activated and it starts reproducing, making more copies of itself.

所以 当接收到正确的信号,恰当的T细胞寻觅到,感染外源病毒的细胞时,首先发生的是,T细胞被激活并开始增殖,制造更多自身拷贝
