查询词典 chromosome

Chromosome condensation is a significant process of cell multiplication and occurs as a prelude to sister chromatid segregation that initiates at the onset of anaphase.

在细胞增殖过程中，染色质集缩是细胞分裂得以正常进行的重要条件，也是后期姊妹染色单体分离的序曲。

It is this that is visible as the typical looped threadlike chromatin material of the nondividing chromosome.

这就是在不分裂染色体中可见的典型的松弛的线状染色质。

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。

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 results indicated that chromosome counting was the most reliable and precise method, however, it was cumbersome and required skilled cytological techniques; The chromocenter size, heterochromatin number, chroloplast number of guard cell and certain plant morphological characteristics are simple and practical methods for ploidydetermination but with some shortages.

结果表明：对体细胞染色体的直接计数法是最可靠的方法，但费时、难度大；叶片气孔大小与倍性无显著相关性；保卫细胞叶绿体数目、体细胞染色中心大小以及异染色质个数与黄瓜倍性密切相关，是简单、快速而有效的倍性鉴定方法；植株的形态学观察也能间接确定植株倍性，但鉴定时期偏晚，精确性较差。

Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87～5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.

以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例，比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹丰富，而与早中期G-带带纹吻合。

Objective To study the sex chromosome copy number alterations in lung cancer.

目的 研究肺癌细胞中性染色体拷贝数的异常。

The results show that the chromosome number 46 takes 56%,and number 40 takes 44% in Ca76/s model.

含46条的占56％，含40条的占44％，共发现6条标记染色体，出现频率为10／10。

For many species, chromosome number is a useful taxonomic character.

对许多物种来说，染色体数目是重要的分类学特征。

Organisms cell chromosome number and structure are important genetic markers,especially in eukaryotic cells.

生物体细胞的染色体数目和结构是生物体重要的遗传标志之一，特别是在真核细胞中。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
