Have had the intense function fromthis the explanation preparation and DNA, matched the body the planearyl residue groups and bases to insert the DNA double spiral plane,caused the plane aryl residue groups and bases the electronic clouddensity to have the change.

由此说明配合物和DNA发生了强烈作用，配体的平面芳基基团插入了DNA的双螺旋平面，导致平面芳基基团的电子云密度发生改变。

Has provided the precise automatic weighing and matches feeding system for the material,the high yield extruder,the precise double spiral plane piling up complex head,the closed-loop control auto-matic vane,has the independent patent in cold system,there is exquisite steadily soaks device,the rotator ,the electronics corona process.

The bases in different environment can lead to different site energies, because of the double helix structure and base sequence in DNA.

由于DNA的双螺旋结构和碱基序列的排列，碱基的不同所处环境，会导致其位点能量的不同。

Here, we demonstrate the benefits of using information about the DNA double-helical stability for motif discovery.

这里，我们证明了使用DNA双螺旋稳定性的信息进行motif发现的优点。

In fact, the double-helical structure of DNA was deduced from crystallographic data.

DNA 分子的双螺旋结构就是通过晶体学实验数据发现的。

In truth, Dr Watson, co-discoverer of the double-helical structure of DNA back in the 1950s, had a point.

事实上，在1950年当沃森博士合作发现DNA的双螺旋结构的时候，他的断言的确有一定的道理。

In 1953,Watson and Crick set forth their hypothesis for the double-helical nature of DNA.

1953年，沃森和克里克阐明了他们关于DNA双螺旋结构的假说。

Measurements of this type suggest that the average value for double-helical B-type DNA is 10.5 bp/turn.

这种类型的长度表明B型双螺旋DNA的平均值为10.5bp每圈。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
