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。

According to molecular theory,all matter is made up of small particles called molecules.

根据分子理论，一切物质都是由叫做分子的小粒子组成的。

In addition, a two-dimernsion host molecular library of amide derivatives of tartaric acid was designed and synthesized.

本论文还设计合成了由20余个酒石酸酰胺衍生物组成的二维主体分子库，并对平行方法筛选主体分子作了一些初步的探索，发现主客体分子识别存在很强的专一性。

A transmissive electr-onmicroscope is used to study the appearance and molecular weight of the monomolecules of xanthan.

认为黄原胶分子在一般情况下具有较规则的二、三、四级结构，论述了其初、高级结构之间的关系，得出了黄原胶分子是由40余个亚基组成的右手双螺旋这一结论，计算出其分子量为6×10~6至25×10~6。

Were used as parents to produce a F2 population consisting of 120 individual plants, which were used to construct a molecular linkage map. On the basis of observing the qualitative and quantative traits of the map population, Two types of DNA molecular marker methods, simple sequence repeals and amplified fragment length polymorphism, were used to construct a linkage map of molecular markers and to map genes of agronomic characters.

多标记基因系T582和T586为亲本，构建了一个由120个单株组成的用于分子标记图谱构建的F_2作图群体，在考察和分析亲本、F_1和F_2群体质量性状和数量性状的基础上，利用SSR和AFLP分析技术，首先对各群体进行DNA分子标记的多态性分析，然后对显示多念性的标记进行连锁分析、图谱构建和农艺性状基因的定位。

You should understand the time signature at the beginning of each composition. It looks like a fraction, consisting of a numerator and a denominator. The numerator indicates the number of beats per measure and the denominator indicates the note per beat.

你应该要认识一首曲子开头的节拍记号，它看起来像是一个分数，由分子与分母组成，分子表示每一段有几拍，而分母表示以哪个音符当作一拍。

Because of the filtering property suggested, two-dimensional periodic screens which were named the frequency selective surfaces have attracted a great deal of attention for many years and have been found various applications, such as band-pass radomes, reflectors of antenna system, polarizers and so on.

「频率选择表面」是由一群在空间中呈周期性排列的金属所组成的二维阵列。由於其滤波的特性，多年来，吸引了大量研究工作的投入。研究中发现，频率选择平面在电磁波的许多频段中，具有广泛的应用。例如在微波中可用於雷达或天线系统，在红外光的频段中则可用於极化器或提升分子雷射的效率。

Louise Arbour, head of the International Crisis Group, says the Sri Lanka model consists of three parts: what she dubs "scorched-earth tactics"(full operational freedom for the army, no negotiations with terrorists, no ceasefires to let them regroup); next, ignoring differences between combatants and non-combatants (the new Icg report documents many such examples); lastly, the dismissal of international and media concerns.

国际危机组织领导人露易丝阿尔布尔，说斯里兰卡模式由三部分组成：她戏称为&焦土战术&的战术（军队完全的自主行动权、绝不与恐怖分子谈判、绝不停火给恐怖分子重整旗鼓的机会）；其次，忽略战斗人员和非战斗人员的差异（国际危机组织一份新报告记录了很多这样的例子）；最后，不予理会国际方面和媒体方面的关注。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
