姐妹

The standard practice is to call the entire structure a chromosome and each of its strands a sister chromatid.

标准的做法是把整个结构称为一个染色体，而把它的各条称为姐妹染色单体。

Methods:Sister chromatid exchangeswere investigated in 44 patients with adult leukemia.

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

An increased incidence of sister chromatid exchanges in peripheral lymphocytes of operating room personnel exposed to waste anesthetic gases has been reported.

已有报道，在暴露于麻醉性气体的手术室工作人员中，外周淋巴细胞姐妹染色体交换的发生率有所上升。

Methods The bone marrow cells of pure Kumming species of mice were used as experimental material in which the micronucleusand sister chromatid exchanges induced by cyclophosphamide were used as an index.

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。
