Histone proteins both protect DNA and regulate genes as they combine with DNA to form chromatin.

组蛋白既保护DNA也在它们与DNA结合形成染色质时调节基因表达。

Chromatin consists of coiled DNA bound to basic proteins called histones and non-histone proteins.

染色质由卷曲的DNA、组蛋白和非组蛋白组成。

Here's a video that animates the acetylation of histone proteins in the regulation of gene expression in cancer cells.

下面的视频是关于在癌症细胞里的常规基因表达是如何进行组蛋白乙酰化作用(acetylation of histone)的。

The change is suggested to be the result of a "histone code" - a process that sees genetic changes made to proteins called histones within cells' nuclei.
