查询词典 sister cell

In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.

我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异，经由子叶面积大小的测量，欧洲苦苣苔成员两片子叶呈现相似的生长速率，因此维持两片子叶等大的特徵，然而堇兰的大小子叶的确具有不同的生长速率，使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。

Objective: To observe the effect of melatonin on frequency of sister chromatid exchange and cell proliferation kenitics in lymphocytes from human peripheral blood in vitro.

目的：观察褪黑素对体外培养人外周血淋巴细胞的姐妹染色单体交换和细胞增殖动力学的影响。

Studies on Sister Chromatid Exchange and Cell Cycles

姐妹染色单体交换和细胞生长周期的研究

Chromosome condensation is a significant process of cell multiplication and occurs as a prelude to sister chromatid segregation that initiates at the onset of anaphase.

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。

Objective: To study the changes of sister chromatid exchange rate in the mutator cell of tumor cell and mutagenized by drug or teratogen.

姐妹染色单体互换(sister chromatid exchange，SCE)检测是细胞遗传学研究领域的一项重要技术。

Genes important for male gametogenesis involved in highly con-served landmark events such as meiotic recombination, formation of the synaptonemal complex, sister chromatid cohesion, spermiogenesis during postmeiotic stages, and checkpoints and factors required for the meiotic cell cycle .

精子发生中的重要基因与一系列精子发生过程中阶段性的细胞事件密切相关，例如减数分裂重组、联会丝复合物的形成、姊妹染色体的结合、减数分裂后精子的变态以及减数分裂周期中的关键点和必需因子等。

Prior to cell division it replicates, and the sister centrioles move to opposite ends of the cell to lie within the spindle-organizing structure, the centrosome.

它在细胞分裂之前复制，其中一个中心粒移向细胞的另一端，组织纺锤体和中心体。
