查询词典 euchromatin

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。

Euchromatin is thought to be actively involved in transcription and therefore protein synthesis, while heterochromatin is inavtive.

异染色质由于折叠压缩程度高，所以被碱性染料染色时着色较深。

Heterochromatin decreased, euchromatin and the proportion of S phase increased in K562-CGI-100 cells, growth curves indicated enhanced cell proliferation.

该重组K562细胞阳性单个克隆在体外稳定传代扩增后作为后续的实验对象。

In DAPI banding pattern, the dark region is generally thought to be euchromatin rich and the bright region is heterochromatin rich. It just provided the experimental foundation for the above deduction.

在DAPI带型中，暗区一般被认为是常染色质较丰富的区域，而亮区为异染色质较丰富的区域，这正好为上述的推论提供了实验依据。

The types of histone methyltransferases, the relationship between methylation of Lysine 9 of H3 and the formation of heterochromatin, gene regulation in euchromatin, and that with DNA methylation, were mainly introduced.

主要阐述了组蛋白甲基转移酶的类型，组蛋白H3中第9位赖氨酸甲基化与异染色质的形成、常染色体中基因表达的调控，以及与DNA甲基化之间的关系，说明了组蛋白甲基化与组蛋白乙酰化、磷酸化的相互关系，指出组蛋白甲基化对维持细胞各种状态的平衡起到极其重要的作用。

Since then, the gene localization has developed from simply being described as at the euchromatin region and heterochromatin region to more complicated nuclear localization. Therefore, the gene regulation attracted more attention now.

因此基因在细胞核内的定位就由原来简单认为的异染色质区和常染色质区发展得更为深入了，基因在细胞核内的定位以及位置的变化与基因表达调控之间的关系也越来越受到重视。

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。

Recognizing euchromatin pattern and smooth nuclear contours which may be better appreciated on a TP can prevent overdiagnosis.

其常染色质聚集及光滑的核膜在液基细胞学涂片中更容易认出，不容易过诊断。贺兰山踏不破，雪花儿融不了。

Most genes reside in euchromatin, which is of relatiely low density and where the DNA is more accessible to the machinery of gene transcription.

大多数基因位于常染色质，结构相对疏松，DNA更易被转录。

It is classified as euchromatin or heterochromatin on the basis of its staining properties, the latter staining much more intensely with basic stains because it is more coiled and compact.

可以按照染色的性能分为常染色质和异染色质。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
