The first three positions were filled by medical inventions or discoveries, the X-ray machine being followed by the discoveries of penicillin and the DNA double helix structure.
排在榜单三甲位置的发明都是医学领域的重大发明或发现。紧随X光机之后的是盘尼西林（青霉素）的发明，以及DNA双螺旋结构的发现。
Whether we really understand DNA is debatable, but Francis Crick and James D. Watson published the first of many papers describing the double helix structure on this day in 1953.
我们是否真正了解了DNA仍值得商榷，但1953年的这一天，弗朗西斯·克里克（Francis Crick）和詹姆斯·D·沃森发表了系列论文的第一篇，阐述了DNA的双螺旋结构。

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 DNA is a double helix and I've only shown you one part of the helix, right? I've shown you one upright strut and a base hanging off of it, but it forms a double helix because complementary strands of DNA strongly associate with one another and that's a very stable structure.
NA是双螺旋,我只是给你们讲了螺旋的一边,我给你们演示,一条链的支柱及碱基团,但其能构成双螺旋,是因为DNA是完全互补的两条链,彼此之间结合紧密,结构异常稳定
