- 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。

- 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。
- Not surprisingly, cohesion is normally established when sister chromatids are synthesized during S phase of the cell division cycle (see the figure). 当然，内聚力通常存在于细胞分裂S期，也就是染色单体形成的时候。
- To investigate the incidence of sister chromatid exchange ( SCE ) and its influencing factors. 探讨影响姐妹染色单体互换(SCE)频率的因素。
- Objective: To study the changes of sister chromatid exchange(SCE) rate in the mutator cell of tumor cell and mutagenized by drug or teratogen. 目的:了解在肿瘤细胞中、一些药物、致畸物引起的突变细胞中姐妹染色单体交换(SCE)率的变化。
- And also did the rate of chromosome aberrance(CA),sister chromatid exchange(SCE) and micronuclie cell (MC) of peripheral blood(P>0.05). 接触组外周血淋巴细胞染色体畸变率(CA)、姐妹染色单体互换率(SCE)、微核率(MC)与对照组比较;差异均无统计学意义(P>0.;05)。
- Methods: Sister chromatid exchange(SCE) freqency was determined in human lymphocytes and plant root tip cells after treatments with pesticides. 方法 :测定蚕豆、大麦根尖细胞和人外周血淋巴细胞姐妹染色单体交换 (SCE)率。
- By means of sister chromatid exchange method (SCE),micronucleus test of bone marrow cells, genetic toxicity of Coprinus comatus was evaluated in mice. 应用小鼠骨髓细胞姐妹染色单体交换（SCE）及微核试验对鸡腿蘑进行遗传毒理检测。
- Methods:Sperm abnormality test, sister chromatid exchange(SCE) test in mouse spermatogonia and unscheduled DNA synthesis(UDS) test in mouse sperms were used. 方法:采用小鼠精子畸形试验、精原细胞姐妹染色单体互换试验和小鼠精子非程序DNA合成试验。
- Purpose and Methods: Single cell gel electrophoresis(SCGE), sister chromatid exchanges(SCE), chromosome aberrations are three methods to determine DNA damage and repair. 目的与方法 :单细胞凝胶电泳技术 (SCGE)、姐妹染色单体交换法 (SCE)和染色体畸变分析法均能被用来检测DNA的损伤或修复。
- BCHI-1 hnd elevated sister chromatid exchange (16.88 time/per cell),the chromosome abnormal rate was 4. 5%, micro nuclei rate was 25%o at normal condition. 该细胞株表现为姐妹染色单体交换增高(16.;88个/细胞);染色体畸变为4
- It is involved in processes such as homologous chromosome pairing, sister chromatid adhesion and separation, and some of the regulation initiated during anaphase. 在细胞有丝分裂和减数分裂中, 着丝粒作为保证染色体正常分裂并分离到子细胞的结构和功能元件, 参与了同源染色体配对、姐妹染色单体黏合、分离及分裂后期启动的调控等。
- Methods: Phenol-sulfuric acid method was used for the determination of the content of polysaccharide, the mouse bone marrow chromosome test and the sister chromatid exchange text. 方法：水提醇沉法提取五味子多糖，0.;1%25活性碳脱色，苯酚-硫酸法测定多糖含量，进行小鼠姐妹染色单体交换及染色体畸变实验。
