helix structure

基本解釋

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.
排在榜單三甲位置的發(fā)明都是醫(yī)學領域的重大發(fā)明或發(fā)現(xiàn)。緊隨X光機之后的是盤尼西林（青霉素）的發(fā)明，以及DNA雙螺旋結構的發(fā)現(xiàn)。
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.
我們是否真正了解了DNA仍值得商榷，但1953年的這一天，弗朗西斯·克里克（Francis Crick）和詹姆斯·D·沃森發(fā)表了系列論文的第一篇，闡述了DNA的雙螺旋結構。

I want to start by showing you this cartoon that you already know about with the structure of a double helix.
我想要給你們看這張卡通模型,你們都知道,這是DNA雙螺旋結構

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是雙螺旋結構,眾所周知,DNA的這種雙螺旋結構,是在我出生的那個年代才被發(fā)現(xiàn)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是雙螺旋,我只是給你們講了螺旋的一邊,我給你們演示,一條鏈的支柱及堿基團,但其能構成雙螺旋,是因為DNA是完全互補的兩條鏈,彼此之間結合緊密,結構異常穩(wěn)定
