And back then, he was studying immunology, the molecular architecture of fevers.

当时，他正在研究免疫学，即发烧的分子结构。

Since its discovery, chemists have been finding out all the different kinds of molecular architecture they can build with their special new Lego blocks.

自从它被发现以来，化学家们一直在寻找他们可以用他们特殊的新乐高积木建造的所有不同种类的分子结构。

Now, just as the word " building" fails to capture the incredible variety of structures that make up any large city, the generic term " protein" gives no clue as to the incredible variety of molecular architectures at the molecular level.

现在，正如“建筑”这个词未能捕捉到构成任何大城市的令人难以置信的各种结构一样，通用术语“蛋白质”也没有提供有关分子水平上令人难以置信的各种分子结构的线索。
