英语语法分析

He and other biologists studying a wide variety of organisms have found that these particular RNA's direct, in large part, the synthesis of histones, a class of proteins that bind to DNA.

他和其他研究多种生物的生物学家发现，这些特殊的 RNA 在很大程度上直接影响组蛋白的合成，组蛋白是一类与 DNA 结合的蛋白质。

Once synthesized, the histones move into the cell nucleus, where a section of DNA wraps around them to form a structure that resembles beads, or knots, on a string.

一旦合成，组蛋白就会进入细胞核，细胞核内的 DNA 片段会将组蛋白包裹起来，形成一种类似串珠或绳结的结构。

The histones are kind of like the spool.

组蛋白就像是线轴。
