着丝粒

The result showed that during mitotic division, the Ser-10 phosphorylated histone H3 start from the prophase and vanished at telophase, remaining mainly in the pericentromeric regions at metaphase and anaphase. During the mitosis the microtubules take on regulated change pattern.

结果显示在小麦根尖细胞有丝分裂过程中Ser10磷酸化的组蛋白H3的出现和消失与染色体的凝集和解凝集的过程存在时空上的相关性，在有丝分裂的过程中这种蛋白在着经线粒上的定位有有助于染色体向两极移动。

RFLP genetic linkage map of wheat recombinant inbred lines derived from W7984 Opata,was used to study QTL of 33 traits associated with water use efficiency.Compared with QTL map of 7 group homeologues chromosomes,the results were showed as follows:nearby the centromeric region of 1A and 1B chromosome,the gene cluster of controlling photosynthetic and root traits were located.

我们利用W7984 Opata重组近交系的RFLP作图群体，对33个与小麦水分利用效率有关的性状进行了QTL遗传图谱比较分析，结果显明：在第一部分同源群染色体（1A，1B）上的着丝粒周围，分布有控制光合作用和根系特性的基因簇。

According to the results of the research,the karyotypes of three species of wingless crickets have common deriving,the variation is due to centric fusion and rission,and pericentric inversion.

的染色体作了比较研究，结果显示，3种无翅类蟋蟀的核型具有一定相似性，核型的差异可能是由于臂间倒位和着丝粒的融合和裂解。

The gene of F46ag is to be cloned and sequenced.

这种着丝粒蛋白的基因克隆、序列测定工作正在进行。

The amounts of some of these proteins were reduced to different extents by HT treatment.

受HT作用，细胞中这些着丝粒蛋白的含量不同程度地降低。

2The two groupers have the Ag-NORs banding on the 24th pair chromosomes.

斜带石斑鱼和橙点石斑鱼的Ag-NORs均出现在第24对染色体着丝粒区。

There was anearlier repli-cation band in the broad,late replication legion W chromosome's long arm,whilst Z chromosome lacked this earlier replication band.

在W染色体长臂近着丝粒处有一个较早的复制带，Z染色体则缺乏这个复制带。

There was a significant difference between Yanbian yellow cattle and Liyan hybrid cattle in the relative length of chromosome, centric index and arm ratio p

经t检验，延边黄牛和利延杂交牛的常染色体相对长度，性染色体相对长度、着丝粒指数和臂比的差异显著p

Multiple genetic changes have been found in ESCC,but little is known about major oncogenes and tumor suppressor genes involved in this disease.To surveying chromosome imbalances in this disease,we analyzed statistically high-frequency chromosomal changes of ESCC from the previous studies by multicolour fluorescence in situ hybridization and comparative genomic hybridization.

为鉴定与食管癌关系密切的基因，本研究从染色体畸变的角度出发，在实验室前期工作及相关文献的基础上，统计分析食管癌染色体畸变谱，发现3、5、8号染色体重排及着丝粒断裂再重组可能是最常见的结构改变，3q、8q增益是最常见的数目异常。

The results demonstrated that the dup(p21) and the del(p11) were of paternal origin and i was of maternal origin. The dup(p21) arose from an unequal sister chromatid exchange. The del(p11) occurred through X chromosom e breakage and deletion machanism.

结果表明，dup(p21)和del(p11)起源于父方，而i起源于母方。dup(p21)是由X染色体姊妹染色单体不均等的互换所引起的，del(p 11)是由于X染色体断裂后丢失所致，i的发生是由于卵母细胞X染色体着丝粒错分裂。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
