音标发音

Their discovery of the double helix is one of two associated with Crick; the other is the genetic code.
他们发现的双螺旋链其中由克里克联想出来，另一个是根据基因密码制作。
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.
在回答另一个问题时，霍金则回顾了科学之美，例如生物学中DNA精致的双螺旋结构，或物理学中的基本方程等。
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.
从远处看，这些基本成分看上去极为相似，因此 DNA 的每一部分的基本形状都是相同的 — 著名的沃森克里克双螺旋结构。

One thing to notice is this part of the double helix that we'll call the backbone.

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

双螺旋
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处于扭曲的八面体中心，pbbt作为桥联配体连接各个结构单元形成一条沿a-轴方向无限延伸的一维双螺旋链，沿着b和c-轴方向每条链上的苯环之间存在着弱的π—π作用，由此形成了二维的双螺旋网络结构。
