染色质

The molecular mechanism of OIS is related to the formation of heterochromatin and DNA-damage check-point response.

它的发生机制与异染色质的形成以及DNA损伤检测点反应的作用相关。

So we concluded that the heterochromatin of X and Y was homologous.

由此我们可以确认，X、Y染色体的异染色质是同源的。

Heterochromatin is dynamically regulated during the cell cycle and in response to developmental signals.

在细胞周期中，异染色质会被进行动态的调节，以响应发育信号。

The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery.

如此大量的结构异染色质的来源及其在染色体组型进化和物种形成中的任务仍是一个谜。

Heterochromatin has shown to be composed largely of short repeated polynucleotide sequences.

异染色质大部分是由短而重复的多核苷酸序列所组成的。

What other functions abundant heterochromatin may perform are still an open question.

而异染色质其他的功能尚未明了。

In fact, the first evidence that histones might be involved directly in formation of heterochromatin was provided by the discovery that

SIR3的C端与核的蛋白质薄层有着相似性并且可以起将异染色质束缚在核周围的作用。

Methylation of histone H3 at lysine 9 has a well-established role in heterochromatin formation and gene transcription regulation.

研究表明，组蛋白H3K9甲基化在异染色质形成及基因转录调控中具有重要的作用。

It contains the largest autosomal block of heterochromatin, which is heteromorphic in 6–8% of humans, whereas pericentric inversions occur in more than 1% of the population.

它具有最大的常染色体异染色质区域，其在6-8％的人群中为异型的，然而中心周围倒位在人群中出现率大于1％。

Karpen and Peng hae identified the molecular pathways that regulate two of heterochromatin's important functions.

Karpen and Peng发现了调控异染色质两个重要功能的分子路径。

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.
