Histones

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

组蛋白的特点是大量的翻译后修饰，这些修饰可基因转录。

2.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组蛋白或鱼精蛋白的特殊类。

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

每个长链DNA与组蛋白和非组蛋白一起构成染色质物质。

4.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.

组蛋白乙和去乙一对功能相互拮抗的蛋白酶——组蛋白乙基转移酶和组蛋白去乙酶负责。

5.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DNA，蛋白质（主要是组蛋白），及少量的RNA组成的线性复合结构，是间期细胞遗传物质存在的形式。
