纺锤丝

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。

In this study, we found interesting two-cell stage embryos, which had a monopolar spindle in one blastomere and a bipolar spindle in the other during the second mitosis in a batch subjected to tetraploidization treatment.

在诱导四倍体过程中，我们发现了有趣的二细胞期胚胎现象，在第二次有丝分期间，它的一个分裂球中有一个单极纺锤体，二另一个有一个双极纺锤体。

The active targets of the aneugens in the cells were not only chromosome and DNA but also all kinds of mitosis apparatuses (such as centriole, kinetochore, microtubule of spindle etc ),centromere and cell membrane.

非整倍体诱发剂在细胞中的作用靶标通常不仅是染色体和DNA，也可包括各种有丝分裂器（如中心粒、着丝点、纺锤体微管），着丝粒和细胞膜。

There are nine bivalents in pollen mother cells at late diplotene or early diakinesis, and the homologous chromosomes essentially arrange on the equatorial plate at late metaphase Ⅰor early anaphase Ⅰ, then the two homologous chromosomes of each bivalent separate from each other and move to two opposite poles drawn by spindle fibers.

在减数分裂双线期末或终变期初，可以观察到9个二价体，在中期I末至后期I初，同源染色体基本排列在赤道板上，然后在纺锤丝的牵引下二价体的两条同源染色体分开，分别移向两极，每一极有9条染色体，从而确认该属植物的染色体基数为x=9。

Such a process is exerted by the spindle and kinetochore during mitosis.

在有丝分裂期间，这样的一个过程受纺锤体和着丝点控制。

CENP-E is a microtubule-based kinesin motor protein located on the outer kinetochore and is responsible for a stable microtubule-kinetochore attachment.

有丝分裂期染色体的运动是由纺锤体微管和位于染色体着丝粒区域的一个特化的结构—动点之间程序化且动态的相互作用而协调完成的。

The centromere contains the kinetochore, a structure involved in the attachment of the chromosomes to the spindle during nuclear division.

着丝点上包含了着丝粒，着丝粒确保细胞在分裂中染色体与纺锤体的整合，发生有序的染色体分离。

Centromere The region of the chromosome that contains the kinetochore, the structure that becomes attached to the nuclear spindle during mitosis and meiosis.

着丝粒：染色体上包含着丝点的区域，在细胞有丝分裂和减数分裂期间与纺锤体相整合的一种结构。

And the chromosome movements in mitosis are orchestrated by dynamic interactions between spindle microtubules and the kinetochore,a multi-protein complex assembled onto centromeric DNA of the chromosome.

有丝分裂过程中染色体的运动和分离又是通过纺锤体微管和位于染色体着丝粒上的动点之间的协同作用来完成的。

We found that EBNA2 can compromise mitotic spindle checkpoint and cause polyploidy in HEp-2, U2-OS and BJAB cells.

我们也发现EBNA2可以在HEp-2、U2-OS、BJAB等细胞中干扰有丝分裂纺锤丝检查点，并且造成多套体。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
