double helix

音標(biāo)發(fā)音

Their discovery of the double helix is one of two associated with Crick; the other is the genetic code.
他們發(fā)現(xiàn)的雙螺旋鏈其中由克里克聯(lián)想出來(lái)，另一個(gè)是根據(jù)基因密碼制作。
In answering another, he wrote of the beauty of science, such as the exquisite double helix of DNA in biology, or the fundamental equations of physics.
在回答另一個(gè)問(wèn)題時(shí)，霍金則回顧了科學(xué)之美，例如生物學(xué)中DNA精致的雙螺旋結(jié)構(gòu)，或物理學(xué)中的基本方程等。
From a distance, these building blocks look very similar, so every piece of DNA you look at has the same overall shape—the famous Watson-Crick Double Helix.
從遠(yuǎn)處看，這些基本成分看上去極為相似，因此 DNA 的每一部分的基本形狀都是相同的 — 著名的沃森克里克雙螺旋結(jié)構(gòu)。

One thing to notice is this part of the double helix that we'll call the backbone.
要注意的是,這兩股構(gòu)成雙螺旋的鏈我們稱(chēng)之為主鏈

The other 98.5% of the double helix was derided as junk, a vestige of the distant evolutionary past.
FORBES: Junkyard Dogs

the form of the molecular structure of DNA, consisting of two helical polynucleotide chains linked by hydrogen bonds and coiled around the same axis DNA

雙螺旋
The Co(II) centers are linked by pbbt ligands leading to the double helix chain. Along b-axis and c-axis directions, weak interactions between adjacent chains also exist between two Py.
中心原子Ni處于扭曲的八面體中心，pbbt作為橋聯(lián)配體連接各個(gè)結(jié)構(gòu)單元形成一條沿a-軸方向無(wú)限延伸的一維雙螺旋鏈，沿著b和c-軸方向每條鏈上的苯環(huán)之間存在著弱的π—π作用，由此形成了二維的雙螺旋網(wǎng)絡(luò)結(jié)構(gòu)。
