有丝分裂的

In organisms showing ALTERNATION OF GENERATIONS, the gametes may be produced by mitosis in the haploid generation, or by meiosis in the diploid generation and give rise directly to gametes or gamete-producing cells.

在表现出明显世代交替的生物体中，配子可能是由单倍体世代发生有丝分裂产生，亦可由二倍体世代减数分裂直接产生配子体或配子母细胞。

Sister chromatid cohesion is fundamental to the faithful transmission of chromosomes during both meiosis and mitosis.

姐妹染色单体粘连是有丝分裂和减数分裂时染色体忠实分离的基础。

Cell cycle is the cell through a series of orderly changes in the cells to achieve cell growth and proliferation process of cell cycle regulation and individual development, differentiation, growth, regeneration, aging and cancer cells is closely related to eukaryotic cell cycle mitosis two key processes, namely DNA replication and sister chromatid evenly assigned to the sub-cells.

细胞周期是指细胞通过一系列有序的细胞内变化，实现细胞生长和分裂增殖的过程细胞周期的调控与个体发育、分化、生长、再生、衰老以及细胞的癌变密切相关真核细胞有丝分裂周期有两个关键的过程，即DNA的复制和姐妹染色体均衡地分配到子细胞中。

Two signals of 45S rDNA were mapped on the mitotic metaphase chromosomes in the F1 hybrids, respectively, and one signal was present on a bivalent during meiotic of synaptene, diakinesis, and metaphase I. We inferred that the two mitotic chromosomes carrying 45S rDNA were homolo-gous pairs.

在有丝分裂中期染色体上2个杂种分别检测到2个杂交信号，在减数分裂粗线期、终变期、中期Ⅰ染色体上45S rDNA位于一个二价体上，说明这两个杂种携带45S rDNA的染色体为同源染色体。

Study on cellular divisional pattern of the A.

有丝分裂时细胞分裂的方式。

The results of the karyotype analysis indicated that the heteromorphic sex chromosomes existed in mitotic prometaphase chromosomes of the early embryos. Zchromosorne was the longest among the total of 56 chromosomes, and usually had twoconstricts at the ...

经对23个分散好、完整的分裂相的分析表明：家蚕早期胚胎有丝分裂早中期染色体中有异型性染色体存在，Z染色体是核型中最长的，通常具有亚端和亚中部次缢痕，W染色体很短，约相当干Z染色体的1／3长。

In wheat, during meiotic division, H3 phosphorylation initiated in special domains at the transition from leptotene to zygotene.

小麦有丝分裂中，分裂早前期，H3磷酸化起始于细胞核内的一些特殊区域。

However, accidental changes in DNA methylation can be transmitted through mitosis or meiosis, leading to epiallelic variation.

但是，DNA甲基化的意外变化能够通过有丝分裂或减数分裂，导致表观变异。

Tetraploid organisms may arise by the fusion of two diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis, or by nondisjunction of the chromoosomes during the mitotic division of a zygote.

四倍体的产生可能是由于两个二倍体配子发生融合，这种二倍体配子又是在减数分裂中染色体不发生分离而形成。四倍体也可能因为受精卵进行有丝分裂时染色单体未发生分离而形成。

Rbkinesin-6 ablated cells could not finish the telophase/cytokinesis phase, and became binuclear/multinuclear cells.

Rbkinesin-6缺失的细胞无法完成有丝分裂末期／胞质分裂，进而转变为双／多核细胞。

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。
