This experiment works on:1.prepare marrow cell chromosome samples;2.take pictures of chromosome in karyon by lens-check;3.Measure the length of chromosome short arm and long arm,calculate the relative length of frog chromosome and the arm index and the position of centromere,with the leven method of outside-body karyon pattern analysis.

本实验制备了骨髓细胞的染色体标本，并且通过镜检拍下一个细胞核中染色体的照片，用leven方法进行体外核型分析，测量每条染色体的长臂长与短臂长，并计算出青蛙染色体的相对长度，臂指数和着丝粒。

Which of the following phases of mitosis is essentially the opposite of prophase in terms of nuclear changes?

在有丝分裂的阶段中，哪种本质上是前期在核变化方面的相反？

Methods Lymphocytes were obtained from healthy donors of different ages, both sexes, and were treated with cytochalasin B. Binucleated cells were hybridized with chromosome 21 specific probe, and simultaneously, chromosome 21 loss and nondisjunction were detected.

用细胞松弛素B处理不同年龄及性别正常人外周血淋巴细胞获得的双核细胞，以21号染色体近着丝粒特异性探针进行荧光原位杂交，同时检测21号染色体丢失及不分离。

The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.

刺鳅，属鲈形目、刺鳅科(Perciformes，Mastacembelidae)，是广泛分布于中国南方的小型淡水鱼类。1998年，我室通过核型分析，首次发现该物种具有明显分化的异形性染色体，其性别决定类型为XX／XY型。1999年，本室通过染色体显带、精母细胞联会复合体观察，再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体，两者不仅已经出现结构异染色质分布上的不同，同时在外部形态上也存在明显差异，识别特征鲜明，在光镜观察下无需显带即能清晰辨认性染色体。

It was found that there was a close relationship between the amount of PMN infiltration and the mitotic index of epidermal cells or the amount of parakeratosis.
