Chromosome segregation in mitosis is orchestrated by dynamic interaction between spindle microtubules and the kinetochore. Proper alignment of chromosomes and their segregation in mitosis also relies on cohesion between sister chromatids.

在有丝分裂中，染色体的分离通过纺锤体与动点之间的相互作用来调节，染色体的正确排列与分离还依赖于染色单体之间的粘连。

Analysing ustiloxins inhibiting plant cell mitosis The inhibition experiment of growth of garlic radicle showed that there were more cells in the telophase stage in the garlic radicle dealed with culture filtrate of Ustilaginodea virens than those dealed with H2O. The cell volume of the former was bigger than that of the latter. So it seemed that ustiloxins could inhibit the cell mitosis, but not in the cell elongation.

毒素对植物细胞分裂的抑制作用分析：用大蒜根尖做抑制试验，发现用稻曲病菌培养滤液处理过的大蒜根尖呈分裂末期的细胞数目明显多于相同条件浙江大学硕士学位论文下对照的数目，抑制率为69%，且细胞明显比对照的细胞大，说明毒素抑制根尖细胞的有丝分裂，但不能抑制细胞的伸长。

Taxol have been used in clinic therapy of breast cancer. Generally speaking, taxol can accelerate the-assemble of microtubule, stabilize microtubule from its discomposing, make mitosis stagnate at G2/M, sequentially interdict the normal mitosis and proliferation of cells, induce cell apoptosis; Besides, a direct function of taxol on cell signal and gene expression, activations of apoptosis genes and expression of proteins can induce apoptosis.

紫杉醇已应用于乳腺癌的临床治疗，一般认为紫杉醇能增强微管聚合，稳定微管防止解聚，使有丝分裂停滞在G2/M期，从而阻断正常的有丝分裂和细胞增殖；除此之外，紫杉醇可以直接在细胞信号和基因表达上发挥作用，活化多种凋亡相关基因的表达，从而引发细胞凋亡。

The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3～11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11～30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1～9μm,so we estimated the size is about 4～27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

棉花FISH技术系统的应用研究。45S rDNA在亚洲棉石系亚1号中期和粗线期染色体上有两对大的信号，在DNA纤维上信号为非连续的念珠状，多个拷贝串联排列，每个拷贝长度大约在3～11μm，推测每个拷贝的实际长度为11～30kb；端粒序列在亚洲棉石系亚1号中期和粗线期染色体端部都有双点信号，在DNA纤维上信号也为非连续的念珠状，不同染色体上信号长度大约在1～9μm不等，推测实际长度为4～27kb；gDNA信号几乎布满整个亚洲棉石系亚1号中期和粗线期染色体，在粗线期染色体上能明显区分出常染色质区和异染色质区，DNA纤维上的信号均为非连续的念珠状。

The events occurring during these stages differ in meiosis and mitosis, notably in that bivalents (pairs of homologous chromosomes) are formed in meiosis, whereas homologous chromosomes remain separate in mitosis.

在减数分裂和有丝分裂中，前期发生的事件是不同的，尤其是二价染色体区别最为明显，在减数分裂中形成，而在有丝分裂中同源染色体是分离的。

Objective To study on the function of mitogen- activated protein kinase and mitosis- promoting factorin the first mitosis of mouse fertilized eggs and the relationship between them.

目的探讨有丝分裂促进因子和丝裂原活化的蛋白激酶在小鼠受精卵第一有丝分裂期中的作用及相互关系。

Most sperm nuclei eventually developed into the male pronuclei, just like the normal sperms, except sperm nuclei in a few zygotes kept dense throughout the fertilization process. Dense chromosome body was seen at the nuclear area during the prophase of first mitosis, and in the middle of spindle at metaphase of first mitosis.

精子入卵后形成精核，大多能够逐渐解凝、液化并膨大，最终形成形态正常的雄性原核，但在第一次卵裂早期退化成浓缩的染色质小体，并在胞质分裂时随机地分配到其中一个子细胞里的分裂沟附近。

The results indicated that γ-rays irradiation with lower doses could promote and stimulate mitosis of root tip cells, and with high doses could inhibit mitosis of root tip cell.

结果表明，在一定范围内，剂量低于60Gy的辐照对毛竹根尖细胞有丝分裂有促进和刺激效应；高于90Gy对毛竹根尖细胞有丝分裂有一定的抑制作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
