染色体

Based on different DNA fragments between Z and W chromosome, the developed PCR method has no risk of the mistrial of those sex identification markers depended on W chromosome, and can omit extra internal control or restriction enzyme deigestion. The DNA-based spindlin gene approach can provide a rapid, exact and low cost method for sex identification in poultry.

本研究以PCR检测家禽Z与W性染色体中之纺缍体蛋白基因intron序列，以其长度的差异来鉴定家禽性别，可避免仅检测W染色体性别鉴定标记的误判，且不需再搭配内部对照，更不需结合限制酶切割法即进行家禽性别鉴定。

Abnormal spindle were formed and chromosomes were separated into several nuclei ofvariable sizes after bi-, or multi-polar divisions in the four cells of tetrads.

原位杂交分析表明，染色体分离前没有经历复制的过程；染色体的两极或者多极分离是完全随机的，没有基因组的特异性。

But a little is about tumorigencity of lymphoma and the relationship between lymphoma development and telomere or telomerase activity.

端粒是真核生物染色体末端的特殊结构，在染色体完整性的保持、定位和复制中发挥重要作用。

Its pattern was similar to that of other teleosts.

拟染色体的形成方式与其它鱼类中拟染色体的形成方式相似。

人类在绘制基因图谱时Y染色体显示的结果让它遭到了很多的批评，但显然Y染色体有反击的毅力和能量。

Sperms may contain an X chromosome or a Y chromosome.

精子可能包含一条X染色体或Y染色体。

Results According to sonograms of 16 cases, Potter taxonomy was adopted.

结果根据16例患者声像图表现，采用Potter分类法，具体有常染色体隐性遗传性多囊肾患者2例，常染色体显性遗传性多囊肾患者7例，多囊性发育不良肾患者5例，梗阻性囊性发育不良肾1例，其他1例。

Epidemiologist Luc Smits of Maastricht University, the Netherlands, who led the study, believes the results support the idea that sperm bearing the male Y chromosome swim faster than sperm with the female X chromosome, and can travel through viscous cervical mucus more easily.

荷兰Maastricht大学的流行病学家Luc Smits领导了这项研究，他相信这项结果支持携带Y染色体的精子游的速度要快于携带X染色体的，且更容易穿过粘性子宫颈粘液的想法。

Hytivus. Although chromosome number of all materials studied was counted to be 2n = 38, the difference in meiotic behaviors between individuals of first selfed progenies were observed, which indicated the difference in the degree of diploidization.

虽然染色体记数的结果表明所有单株的染色体数目都为38条，但是花粉母细胞的减数分裂行为在单株间的细小差异也被观察到了，这表明各单株间存在较小的二倍化程度的差异。

The polytene chromosomes found in the salivary gland cells are among the largest chromosomes known today.

唾液腺细胞中的多线染色体是目前已知的最大染色体之一。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
