histone

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

组白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.

与去氧糖酸结合者通常属于被称为组白或鱼精白的特殊种类。

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

每个长链DNA与组白和非组白一起构染色物。

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DNA，白（主要是组白），以及少量的RNA组的线性复合结构，是间期细胞遗传物存在的形式。

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.
