查询词典 nucleosome

In eukaryotes, DNA left-handed chirality by means of histone proteins around octamer to form a stable nucleosome structure.

在真核生物中，DNA按左手手征性的方式，缠绕在组蛋白八聚体的周围，形成稳定的核小体结构。

Histones, as basic components of nucleosome, are essential to chromatin structure and function.

组蛋白作为核小体的基本组分，是染色质的结构和功能必需的。

Nucleosome is the basic unit of chromatin.

核小体是染色质的基本单位。

The concept of chromatin and chemic compose; chromatin proteins; the essential about the structure of nucleosome; euchromatin and heterochromatin.

二 染色质的概念及化学组成；染色质蛋白质；核小体结构要点；染色质包装的结构模型；常染色质和异染色质。

Each of these bundles is called a nucleosome, and many nucleosomes are bound together by the continuing strand of DNA, which forms a string of beads that further coils to form one of two kinds of chromatin, either euchromatin or heterochromatin.

所有细胞核的最显著的特点就是染色体，由DNA和组蛋白所组成的染色质构成，DNA绕行在由4个相似的组蛋白分子结合而形成的柱状的芯上，这一结构称为核小体，核小体之间由连续的DNA链连接，形成串珠样结构，进一步盘曲形成常染色质或异染色质。

These variants change the conformation and stability of nucleosome to facilitate transcriptional activation or deactivation, DNA repairing, heterochromatin formation, and others.

这些变体通过改变核小体的空间构象和稳定性，决定基因转录的激活或沉默，DNA的修复，染色体的异染色化等。

HIRA may function in regulating chromatin structure, nucleosome reassembly and cell cycle progression by the interactions of its different domains with different proteins.

HIRA可通过其不同的结构域与不同的蛋白质相互作用，来参与调节核小体的组装、染色质的结构及细胞周期的进程等。

Genomic DNA in eukaryotic cell is organized into nucleosome array and further packaged into higher-order structures. Each nucleosome is composed of a stretch of approximately 147bp DNA wrapping around a histone octamer, and neighbored nucleosomes are connected by linker DNA with length varies from 20bp to 100 bp.

中文摘要真核生物的基因组DNA能够与组蛋白形成核小体结构，这些核小体结构在基因组上线形排列，并进一步折叠成更加紧密和复杂的高级结构。
