double-helix

基本解釋

The structures are made from bundles of double-helix DNA strands.
這些結(jié)構(gòu)是由一束束雙螺旋DNA鏈構(gòu)成。
He'd also provided Watson, without Franklin's knowledge, with her key photograph, which showed -- for the first time -- the double-helix shape that underlies the structure of DNA.
他并且背著弗蘭克林，把她拍攝的關(guān)鍵照片提供給沃森，這張照片表明——第一次表明——構(gòu)成DNA結(jié)構(gòu)的是雙螺旋狀態(tài)。
From the surface it looks like nothing more exciting than a stationary grey barge; but below are two spinning turbines, known as foils, which look like a whirling carbon-fibre double-helix.
從表面上看它頂多像個(gè)固定的灰色拖船；但在底下有兩臺(tái)旋轉(zhuǎn)渦輪機(jī)，外號(hào)薄片，看起來像一個(gè)旋轉(zhuǎn)的碳纖維雙螺旋體。

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.
核酸分子雜交表示,DNA在變性狀態(tài)下可以恢復(fù)活性,和與其配對(duì)的單鏈形成穩(wěn)定的雙螺旋結(jié)構(gòu),只有在完全配對(duì)時(shí)才會(huì)發(fā)生這種情況

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(jié)構(gòu),眾所周知,DNA的這種雙螺旋結(jié)構(gòu),是在我出生的那個(gè)年代才被發(fā)現(xiàn)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.
現(xiàn)在要記住只有四種不同的顏色,在雙螺旋DNA的卡通模型上出現(xiàn),我們剛說過這個(gè),我告訴你們的這些顏色,它們代表不同的堿基,不過有五種堿基

Antisense drugs are named after one of DNA's two strands in its double-helix structure, which are known as sense and antisense.
FORBES: Antisense and Sensibility

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

Base excision repair is to excise and restore bases so thatgenetic protein could restore normal DNA double-helix structure, thus it prevents genetic mutation and keeps the genetic stability.
堿基切除修復(fù)是通過切除修復(fù)堿基,使基因重新恢復(fù)正常的DNA雙螺旋結(jié)構(gòu),從而防止基因突變,維持遺傳穩(wěn)定性。
