It's a mixture of things, including a lot of different hydrocarbons, which are non-polar chains.

这一物，包含许多不同类碳氢化物，它们都非极性链状结构。

Polymers are long chain-like molecules that are made up of smaller repeating links.

聚物由较小重复链组成链状分子。

And that means that you can create really complex chains, really complex structures with that carbon.

这意味着你可以用碳创造出非常复杂链状结构，非常复杂结构。

And my specialty was messenger RNA. Like proteins, messenger RNAs are long chainlike molecules composed of building blocks.

我专使 RNA。 与蛋白质一样，使 RNA 由构件组成链状分子。

Now, you need to look very carefully at the join between the two liquids, and you'll see tiny white strands and filaments forming.

现在，你需要非常仔细地观察这两液体之间连接处，你会看到微小白色链状和细丝形成物。
