The molecular version of semitrucks are proteins aptly named motor proteins, that can walk along microtubules, dragging sometimes huge cargoes, like organelles, behind them.

半挂式卡车的分子版本则被贴切的称为“马达蛋白”，它们能在微管上行走，有时候在身后拖着大型“货物”，比如说细胞器。

This particular motor protein is known as dynein, and its known to be able to work together in groups that almost look, at least to me, like a chariot of horses.

这种马达蛋白叫做动力蛋白，能够以小组为单位工作，至少在我看来，几乎和战车的马匹一样。
