染色体

During anaphase I of meiosis pairs of chromatids still connected at their centromere move to the spindle poles.

在减数分裂后期 I 中，由于纺锤丝的牵引，使成对的同源染色体各自发生分离，并分别向两极移动。

The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

The yield, quality, resistance and chromosome characteristics of the hybrids were analyzed, and the improvement of the grasses using gene introgression, androgenesis and genetic modification methods was introduced. The latest advance in GISH, genetic map construction and QTL of Festulolium hybrids were described here.

本文总结了黑麦草羊茅杂种高产、优质、抗性强的优势；分析了杂种染色体配型特点；重点介绍了通过基因渗入、雄核发育和转基因手段改良牧草的方法；对黑麦草羊茅杂种基因组原位杂交、分子标记和遗传图谱建立、数量性状位点分析等分子遗传学的最新研究进展进行了综述。

The number of theromosomes per nucleus is characteristic of the species except in aneuploid plants.

除了少数非整倍性的植物，细胞核内染色体的数目是物种的重要特征。

A cell or an organism characterized by an aneuploid chromosome number.

有多于单倍体两倍染色体的细胞或有机体。

It has been proposed that extra centrosomes generate CIN by promoting multipolar anaphase, a highly abnormal division that produces three or more aneuploid daughter cells.

人们长期所持的一个观点是，额外的中心体通过诱导混乱的多极纺锤体组装和非对称的细胞分裂来促使染色体错误分离。

Chromosome 17 aneuploidy was detected in 19 cases (38%).

结果：在50个样本当中，8个样本（16％）的HER2/neu基因扩增被观察到，19个样本（38％）的染色体17非整倍体被观察到。

While there is no repair mechanism for aneuploidy, protective processes exist to prevent chromosome instability during cell division.

虽然没有修复机制，非整倍体，防护过程存在，以防止染色体不稳定性在细胞分裂过程。

Objective: To explore the reliability of the method PRINS for detection of spermic aneuploidy .

目的：探索应用引物原位标记技术分析精子染色体非整倍性的可靠性。

Objective:To study the centromeric dots variation of HEC1B cells and its relationship with aneuploidy aberration.

中文摘要：目的：探讨人子宫内膜癌细胞HEC1B染色体着丝粒点的变异与其非整倍性畸变的关系。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
