Histones

Histones are characterized by numerous posttranslational modifications that influence gene transcription.

蛋的特点是大量的翻译后修饰，这些修饰可以影响基因转录。

The proteins that combine with DNA are generally of characteristic types called histones and protamines.

与去氧核糖核酸结合者通常属于被称为蛋或鱼精蛋的特殊类。

Each long strand of DNA combines with histones and nonhistone proteins to make up the substance chromatin.

每个长链DNA与蛋和非蛋一起构成染色质物质。

Chromatin The loose network of threads seen in nondividing nuclei that represents the chromosomal material, consisting of DNA, protein (mainly histone), and small amounts of RNA.

间期细胞内由DNA，蛋质（主要是蛋），以及少量的RNA成的线性复合结构，是间期细胞遗传物质存在的形式。

The acetylation and deacetylation of histone is charged by a pair of protea se with antistatic function on each other,which are histone transacetylase and histone deacetylase.

蛋化和去化由一对功能相互拮抗的蛋酶——蛋基转移酶和蛋去化酶负责。
