Even when the level of a molecule seems to predict a drug's success, a test may prove unreliable.
甚至当分子层面似乎预示药物的成功时，一项测试也许会证明其不可靠。
But even the keenest readers are unlikely to suffer too much of a burden, as a full library of e-books weighs no more than a single molecule of DNA.
不过即使是感觉最敏锐的读者也不会为这一负担感到承受过多，因为即使是相当于整个图书馆容量的电子书，重量也不会超过一个DNA单分子。
So every atom. Or even if it's a molecular crystal, every molecule, they're all in the ground state.
那么每个原子，或者说对于分子晶体，每个分子，他们都处于基态。
Even one gas molecule can break a silicon-oxygen bond in glass, generating a defect, said Carlo G. Pantano, a professor of materials science at Pennsylvania State University.
“一个气体分子就可以破坏玻璃的硅氧键，并诱生一个缺陷。”Pennsylvania州立大学的材料科学教授CarloG . Pantano说。
So when they form, the histones are stripped off and replaced with another molecule called protamine, which shapes the DNA into an even tighter bundle, where the genes cannot be read.
所以当他们成形的时候，组蛋白被脱离并且被一种叫做鱼精蛋白的分子代替。它可以把DNA组装成更加紧密的一束，这些基因是无法被阅读的。
This is very easy molecule because we know exactly where to put them without even having to think, we only have one option, and we'll make a triple bond between the carbon and the nitrogen.
这个分子非常简单，因为我们知道应该把它们放在哪里，甚至不用去想，我们只有一个选择，我们将在碳与氮之间形成一个三键。
The lucky ones among his opponents was just be thrown into some dungeon or other full of mold and moisture, but barely even the molecule of eatable food.
幸运一点的对手可能会被关进满是霉菌、充满湿气的地牢——但那儿几乎连一点可吃的食物都没有。
A metabolic end-product form our own body called adenosine is the key molecule that locks up fat, reduces muscle activity, and even makes the use of sugar by the muscles less efficient.
我们自己身体上有一种叫腺苷的新陈代谢产物，这种物质是一种关键的分子，它的功能是锁住脂肪的释放，减少肌肉的活动，结果导致肌肉不得不低效率地低利用糖来提供能量。
