This process, which is shown schematically here, as a vesicle fusing with the cell membrane and then dropping its neurotransmitter only happens when an action potential reaches the end of the axon.

这一过程 扼要地展示在这里,小泡同细胞膜融合,释放其神经递质,这只发生在动作电位抵达轴突末梢时

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

Now if I put them in contact with one another, the plasmid that's been opened and fragments of the DNA - special fragments that I've produced with the same restriction enzyme, they'll have the same sticky ends, they will naturally hybridize with one another.

如果我让它们互相接触,已经切开的质粒和DNA片段--,这DNA片段是我已用同种限制性内切酶,处理过的特别片段,这两者会有相同的粘性末端,它们会自然地相互杂交
