染色体

At anaphase the dicentric chromatid will form a bridge and the acentric a fragment , both of which can be scored.

在后期双着绿点染色体将形成一个桥，无着绿点染色体单体形成一断片，此两者均可记录下来。

To accomplish this, sister chromatids must segregate together during the first meiotic division , which requires that sister chromatid cohesion persists at centromeres.

实现减数分裂，姐妹染色体必须在第一次分裂联会，这过程姐妹染色体在着丝粒结合。

False sister chromatid separation and chrosomal instability may be caused by abnormal centrosome, which may make bipolar spindle abnormal.

异常中心体可产生纺锤体异常，使染色体错误分离，引起染色体不稳定性和非整倍体的形成。

The results also showed that the E chromosome expressed dosage effect on promoting homoeologous chromo some pairing.

同时，在促进小麦部分同源染色体配对作用上，E染色体具有剂量效应。

Telomeres, short tandem repeat sequences at the ends of eukaryotic linear chromo somes, function to stabilize chromosomes.

端粒是真核细胞染色体末端的重复序列，对维持染色体的稳定性具有重要作用。

The percentage of the cell observed chromosome lagging in A1 and the percentage of abnormal cell in TI showed a greatly significant positive correlation. That may demonstrate chromo

相关分析表明后期Ⅰ染色体滞后细胞比率同末期Ⅰ异常细胞比率呈极显著的正相关，推测后期Ⅰ染色体分离和末期Ⅰ微核形成可能是由相同的显性单基因或主效基因控制。

The chromosome number is duplicated in later stage only as chromatids are separated to form separated chromosomes.

染色体数目只在较后期当染色单体被分离而成为独立的染色体。

Some problems related to "variation of chromosome number" in some teaching materials of genetics are presented in this article.

指出了高校有关遗传学教材"染色体数目变异"一节中，部分概念如单倍体、染色体组、非整倍体等存在的概念表述不清、前后矛盾等问题，并提出了相应的修改意见。

These cells often have a variable chromosome number .

这些细胞的染色体数目不等，（称为"非倍数染色体"。

It yields an accuracy rate of over 90% for X chromosomes, and over 80% for Y chromosome.

它会产生一个以上的X染色体，90％的准确率，超过80％的Y染色体。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
