1·It shows a high a-helix structure.

螺旋结构含量高。

2·From the STMimages, we could see clearly the helix pitch and helix diameter of helix structure.

由STM图象中我们能清晰地观察到螺旋结构的螺距与螺径。

3·The DNA is made up of two pieces of nucleotide chains, which is double helix structure with complementary pairing of the bases and winding each other.

沃森一起为脱氧核糖核酸的分子 结构提出了双 螺旋这种 螺旋模型。

4·An article on the letters was published Wednesday in the journal Nature, focusing on those related to the discovery of DNA's double helix structure in 1953.

信件里的一段文章在周三由自然杂志刊发，内容侧重于与1953dna双螺旋结构的发现有相关的模型。

5·The firstthree positions were filled by medical inventions or discoveries,the X-ray machine being followed by the discoveries of penicillinand 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。

6·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。

7·Just like does not have the DNA double helix structure discovery, has not inherited the transmission transmission the central dogma, also does not have today's molecular biology.

正如没有DNA双螺旋结构的发现，就没有遗传传达传递的中心法则，也就没有今天的分子生物学。

8·Structurally, DNA is composed of two strands that intertwine to form a spring-like structure called the double helix.

从结构上讲，DNA是由两条链相互缠绕构成弹簧状结构称为双螺旋。

9·Maryland-based Tilley warns against using English ivy (Hedera helix), which adheres tenaciously and is aggressive enough to move beyond its support structure and enter a building through windows.

马里兰的Tilley提醒不要栽植英国常春藤（洋常春藤），它会顽强附在支撑结构上并凶猛地越过支撑结构从窗户进入到建筑物内。

10·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.

他并且背着弗兰克林，把她拍摄的关键照片提供给沃森，这张照片表明——第一次表明——构成DNA结构的是双螺旋状态。
