查询词典 meiotic

In addition, the journal publishes key papers on chromosome aberrations in somatic, meiotic and malignant cells of man and other animals.

Based on its expression pattern, we propose that this gene may involve in meiotic and postmeiotic processes during mouse spermatogenesis.

这种表达特征暗示了Peat在减数分裂或减数分裂后期起作用。

Meiotic chromosomes with clear configuration and intact amount were selected.

用Lucia染色体分析软件和Image J对其绝对长对和相对长对进行了测算。

The chiasmata observed during the later stages of the meiotic prophase are cytological evidence of earlier cross-over events.

在减数分裂前期末所看到的交叉是在这以前发生了互换事件的细胞学证据。

The cytogenetics of interspecific hybrids among the four cultivated cotton species were studied in this paper and results are as follows: The diploid interspecific hybrid (G. arboreum×G. herbacium) F〓 had a four-chromosome-ring at the meiotic metakinesis. The synapses of tetraploid hybrid (G. hirsutum ×G. barbadense) F〓 was found to be regular, which mainly formed bivalents, sometimes some univalents, multivalents and chromosome bridge.

四个栽培棉种间杂交种F〓的细胞学观察结果表明，F〓减数分裂中期Ⅰ，形成一个环状四价体，直接证明了亚洲棉与草棉之间存在一对相互易位；F〓减数分裂中期Ⅰ联会基本正常，主要形成二价体，偶尔出现一些单价体和多价体，以及染色体桥。

In mixoploid plants, somatic cells with 2n=25~29 were most frequent except for a few haploid cells (2n=19) and chromosome doubling cells (2n=50~60). Abnormal chromosome behaviors were observed in pollen mother cells from mixoploid BI-1 and haploid, including chromosome bridges, laggard chromosomes, meiotic cycle asynchrony and unequal separation of chromosomes.

对混倍体植株BI-1和单倍体植株的花粉母细胞(Pollen mother cells，PMCs)减数分裂染色体行为观察发现，高频率出现染色体落后、染色体桥、染色体分裂周期不同步、不均等分离等异常染色体行为。

Confocal laser scanning microscopy used to localize the hsp70 protein in oocytes and embryos revealed that the distribution of hsp70 in the ooplasm of immature and mature oocytes is unaffected by exposure to decreased or elevated temperatures and that this protein was closely associated with the meiotic spindle indicating its possible role in stabilizing this structure, hi eight-cell embryos derived under control conditions, hsp70 was evenly distributed in the cytoplasm but appeared as aggregates in some embryos exposed to elevated temperature.

此蛋白均匀地分布在两种细胞的胞浆中。此形态特点与减数分裂期纺缍体有关，由此表明hsp70在中期Ⅱ期，具有稳定这种结构的作用。在对照组8细胞胚中，hsp70均匀地分布在胞浆中，而在处理组一些胚胎内，hsp70则发生凝集。

In order to obtain viable tetraploids, which remains a major challenge worldwide, research on spindle organization and chromosome behavior was carried out mainly in zhikong scallop, Chlamys farreri, a typical commercially important species which is being cultured in North China Sea. Immunofluorescent technique and laser scanning confocal microscopy has been developed for observation of both microtubule organization and chromosome segregation. Orcein squash method was also used for chromosome observation. A series of complicated configurations of the meiotic spindle and associated patterns of chromosome segregation, including tripolar and seperated bipolar segregation, were found in developing eggs following the inhibition of the first polar body.

为了攻克可存活四倍体人工培育技术的国际性研究难题，本研究选取了我国北方海区的典型经济贝类栉孔扇贝为主要研究对象，建立了一套免疫荧光染色和激光扫描共聚焦显微技术，结合使用染色体地衣红压片观察技术，对第一极体受抑制的受精卵的减数分裂纺锤体装配、染色体分离动态进行了研究，发现了一系列特殊的纺锤体装配及相应的染色体分离行为，包括三极分离、独立二极分离等分离类型，从亚细胞水平上阐明了四倍体形成的细胞学机理。

These abnormal changes mainly occurred at two stages:(1) at meiotic prophase, almost half of Peiai 64S microsporocytes exhibited aberration, with sparse free ribosomes, underdeveloped mitochondria and many swollen endoplasmic reticula.

这些变化主要发生在两个阶段：（1）减数分裂前期，约半数的小孢子母细胞的胞质出现异常，游离核糖体稀少，并具有不发育线粒体和大量泡状内质网。

Under normal temperature, anthers of not fertility restoration stopped developing in the stage of archesporical cell; 1-2 comers of a few anther could differentiate and form archesporical cell, sporogenous cells and microspore mother cell, but microspore mother cell disintegrated on the first meiotic division.

常温下，未发生育性恢复的花药在孢原细胞期就停止发育；少数花药1~2个角隅处可分化形成孢原细胞，造孢细胞，花粉母细胞，但花粉母细胞在减数分裂的第一次分裂时解体。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
