nucleosomes 中文意思是什麼
nucleosomes
解釋
第十九章 核小體-
The nucleosomes are coiled into a solenoid structure.
核小體可以捲曲成螺線管的結構。 -
Epigenetic modification of the genome ensures proper gene activation during development and involves : genome methylation changes ; the assembly of histon and histone variants into nucleosomes and remodeling of other chromatin - associated proteins such as linker histones, polycomb group, nuclear scaffold protein, and transcription factors
這些染色質的再程序化包括dna的甲基化和核小體組蛋白的乙酰化等。組蛋白乙酰化在染色質結構調節、 dna復制、基因轉錄、細胞分化及癌細胞發育都有研究，但在克隆動物中卻是一個有待深入探索的領域。 -
As rna polymerase ii leaves a gene promotor to transcribe the coding region, it faces many obstacles, including nucleosomes
當rnap離開基因的啟動子轉錄編碼區時，遇到包括核小體在內的多種障礙。 -
Yet despite this effort, there has yet to emerge a unifying mechanism by which nucleosomes are remodeled during gene regulation
然而，現在還未能給出一個較為統一的機制來解釋在基因調控過程中核小體如何發生重構。 -
Dna wraps around histones in left - handed way and forms nucleosome structure. many nucleosomes are linked together like " prayer beads "
Dna分子以左手的方式纏繞在組蛋白分子上，形成核小體結構，多個核小體象「念珠」一樣串聯。 -
The last seven years have spawned a vast amount of data on the enzymes that remodel and modify nucleosomes and the rules governing how transcription factors interact with the epigenetic code on histones
在過去的7年中，科學研究提供了大量的有關以下兩個方面的數據： （ 1 ）具有重構和修飾核小體功能的酶，以及（ 2 ）轉錄因子如何同組蛋白上的表觀遺傳編碼相互作用的機制。
