The second drawer began to fill and as it did I wondered whether there were bigger discoveries out there, not just species, but life that depends on things thought to be useless, life even without DNA. I started a third drawer for these big discoveries.
第二个抽屉开始被填满。此时我在想外头是否还有更大的发现,不只是物种,还有依赖于人们认为无用的东西的生命以及甚至没有 DNA 的生命。我为这些重大发现设立了第三个抽屉。
"I asked, What's the probability that I would see a human DNA polymerase [protein] sequence and another protein with an E. coli DNA polymerase sequence?" he explained.
他进一步解释道:“我要问,我能看到不同的人类DNA聚合酶(蛋白质)系列和另一种大肠杆菌DNA聚合酶序列的可能性有多少吗?”
I talk about the DNA and the individuals as if they were alive.
当谈到DNA和个体时,我把它们当成有生命的一样。
DNA is a double helix, you know this, the double helix was--the structure of DNA was discovered about the time that I was born you've always lived with it.
NA是双螺旋结构,众所周知,DNA的这种双螺旋结构,是在我出生的那个年代才被发现的,它就是你生命的一部分
Now remember that there were only four different colors in the cartoon of the DNA double helix that we talked about and I told you that those colors are really - represent the bases but there's five of them here.
现在要记住只有四种不同的颜色,在双螺旋DNA的卡通模型上出现,我们刚说过这个,我告诉你们的这些颜色,它们代表不同的碱基,不过有五种碱基
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
