The results showed that the optimal combination of three factors and three levels in the detection of triploid Haliotis discus hannai by using chromosome specimens from blood cells of living bodies was: PHA treatment time 18h, PHA concentration 0.04% and sampling time 22:00-24:00. The order of the three factors was PHA treatment time → PHA concentration →sampling time.

根据正交实验直观分析结果，得出用血细胞直接制备染色体标本进行三倍体皱纹盘鲍活体倍性检测的最优组合：PHA处理时间18h、PHA浓度0.04%，抽血时间22：00-24：00，3因素的主次顺序：PHA处理时间→PHA浓度→抽血时间。

Capitata L., were dispersed along the chromosome lengths, with a predominant distribution in the pericentromeric or proximal regions and some heterochromatic arms.

大基因组的玉米和大麦的所有染色体都被密集地标记，并在染色体全长显示出强标记区与弱标记或不标记区的交替排列。

The origin of the heterochromatic regions on the long arm of maize B chromosome was studied in two ways: the Southern signals of the CL-repeat; and its deletion, insertion, and mutation variants.

本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

"Think about a chromosome as being a highway," says Aramayo. In order to function properly, some sections of the highway must have illumination, which means DNA must be expressed, whereas other sections must not have illumination, which means DNA must not be expressed, or that the region must be heterochromatic.

Aramayo说，我们可以将染色体想象成一条高速路，为了正常运行，高速路的一些区段需要照明，也就是说DNA必须被表达；而其它区段则不需要照明，即DNA不需要表达，或这些区段必须被异染色质化。。。。。。。

The origin of the heterochromatic regions on the long arm of maize B chromosome was studied in two ways: the Southern signals of the CL-repeat; and its deletion, insertion, and mutation variants.

中文摘要本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

These sequences possessed highly copy number in the genome and were named as RMX1-6 individually. When these sequences were hybridized to chromosomes of spiny eel, RMX6 was proved to be sex chromosome specific and it only located in heterochromatic regions.

在随机挑取的三百多个克隆中，分离得到了6个高度重复序列，它们在基因组中存在较高拷贝数，按照发现顺序分别命名为RMX1—6(Repetitive sequence inMicrodissected X chromosome)。

There are two traditional views about the processes that maintain B chromosome polymorphisms in populations at present, which are the parasitic model and the heterotic model.

目前有关B染色体在居群中数目多态保持有2种传统观点：杂合优势模型和寄生模型。

Results indicated that suppression of malignancy was observed in the hybrid cells, they became differentiated morphologically and functionally by:(1) changes in histochemical staining, nucleus-cytoplasm in ratio, and increase in cell size and nucleal heterochromation, but decrese in cell surface microvilli and number of nucleoli;(2) decrease of growth rate, mitotic index and DNA synthesis rate;(3) loss of the ability to growth in soft agar medium, and non-tumorigenic under heterotransplantation to nude mice;(4) reduction of chromosome number mainly of rat derivative and decrease in chromosomal aberration rate.

实验结果表明：（1）杂交细胞出现瘤细胞与网织红细胞杂交同样的表型逆转及去恶性化特征，主要表现在细胞体积增大、核质比例减小；DNA合同速率降低、分裂指数下降，细胞生长显著减慢；在软琼脂中不形成集落，在裸鼠体内失去了长瘤能力。

Classically, the skin lesions occur perinatally in four successive stages: inflammatory vesicular (stage 1), verrucous (stage 2), hyperpigmented (stage 3), and scarring (stage 4), along the lines of Blaschko, reflecting the somatic mosaicism of X-chromosome inactivation in female patients.

典型的皮肤表现发生在周产期并可区分为四个阶段：发炎水泡，疣状增生，色素沉著和疤痕形成，而这些病灶都沿著Blaschko's line分布。它代表了女性患者身上一种嵌合型X染色体异常的现象。

Main parameters and methods of chromosome preparing with wall degradation hypotonic technique in cucumber were studied,and a suitable method was established.

以黄瓜卷须为材料，对黄瓜染色体制片中的一些主要参数和方法进行了研究，建立了黄瓜染色体制片的系统操作规程。

We got alerted a couple of times while we were down south that HETs were on the way to bring us back up north because things were going to go hot again, but it was just rumors.

南下的途中我们不只一次得到警告说重型装备运输车将拉着我们重新北上，因为局势正在变得重新紧张起来，但这只是谣传。

It's the one where they find the ghost in the salt mine.

这一集是演他们在盐矿找到鬼
