双语例句
- In eukaryotic cells, the fundamental unit of chromatin is nucleosome, which is composed of a histone octamer with two copies of HA, HB, H and H and base pairs of DNA.
真核细胞中，核小体是染色质的基本单位，它由两个拷贝HA、HB、H和H所组成的核心组蛋白八聚体，及缠绕于其上的bpDNA构成。 - Cage hexahedral silsesquioxane ( T 8), an octamer, each of its sides consists of silicon and oxygen ring. From which, many kinds of macromer and related inorganic/ organic nanocomposites containing inorganic silicon dioxide core have been prepared.
笼型六面体倍半硅氧烷（T8）是一类每个面都由硅氧八元环构成的六面体，从它出发可制得以二氧化硅为核心的大分子单体以及无机/有机纳米复合材料。 - In all eukaryotes, DNA wraps around a histone octamer in a left-handed way, forming 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。 - The octamer formation in vivo is related to cell growth process. During the log-phase of cell growth, the specific activity of nitrogenase is increasing, and the tetramer is the major form of molybdenum-iron protein.
在细胞生长过程中，胞内钼铁蛋白两种聚合体的相对含量出现规律性变化：在对数期，细胞固氮酶比活力成上升趋势，而钼铁蛋白主要以高活力的四聚体形式存在； - We suggest that, the octamer of molybdenum-iron protein is a possible metablite in regulation of nitrogenase activity, the conversion from the tetramer to octamer will cause the decrease of nitrogenase specific activity in vivo.
我们推断，生长过程中胞内钼铁蛋白聚合态的变化可能是调节固氮酶活力的一种方式。 - Nucleosome dynamics, one of the core areas of histone protein research projects, is largely concerned with the interaction between DNA and histone octamer and properties of the formation of nucleosome complex.
核小体动力学主要研究DNA与组蛋白的相互作用下核小体受力、结构形成过程，是蛋白质组研究计划的核心研究内容之一。 - In eukaryote, genomic DNA is packaged in chromatin by twining with histone octamer.
基因组DNA包含了绝大部分的遗传物质，对于真核生物而言，DNA缠绕组蛋白八聚体形成核小体，进而被包装在染色质内。 - The results show that the salt concentration has a great effect on the wrapping process of DNA around histone octamer.
研究结果表明：DNA链与组蛋白的缠绕受溶液浓度影响。
