减数分裂的

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。

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。

To eplore the relationship between Dynein and the formation of meiosis error of oocytes, the immature mouse oocytes were in vitro cultured with a known dynein ATPase activity inhibitor- sodium orthovanadate to detect the changes of maturation rate, and semi-quantitative RT-PCR and single cell RT-PCR were performed to detect the alteration of the cyclin B1 mRNA level.

为探讨Dynein与卵母细胞减数分裂错误形成的关系，采用小鼠卵母细胞体外培养成熟技术和半定量RT-PCR方法，分别检测Dynein抑制剂-原钒酸钠对卵母细胞成熟率和cyclin B1基因转录水平的影响。

The perivitelline space was narrow at GV stage and there were many microvillus penetrating zona pellucida between oocyte and cumulus cells.

在减数分裂启动过程中，小鼠卵母细胞内也发生相应的形态学上的变化。

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。

But, there was no Ca(superscript 2+) precipitate in tapetal cells of Zhenshan 97B at the pollen mother cell stage and the meiosis stage and the Ca(superscript 2+) precipitates in tapetal cells mainly deposited in the disaggregated cytoplasm.

而保持系绒毡层细胞遮花粉母细胞时期和减数分裂时期细胞内没有Ca(上标 2+)沉淀；单核花粉时期绒毡层细胞内的Ca(上标 2+)沉淀主要分布在解体的细胞质内。

Terminalization The movement of chiasmata to the end of the bivalent arms, a process that may occur during late prophase I of meiosis.

交叉移端：发生在第一次减数分裂后期，染色体交叉向二价体染色体臂的末端移动的过程。

Theoretical investigations suggested that the major bottleneck in narrowing down the confidence interval of QTL location is the limited number of informative meioses obtainable in most mapping populations of traditional methods.

理论研究表明，传统方法中作图群体有限的有效减数分裂数是进一步缩小QTL置信区间的一个瓶颈。

Cytologic results showed that chromosome numbers of root cell are 2n 56, and 28 bivalents can be observed at PMC MI in the six 8x Trititrigia.

细胞学鉴定结果表明，6个八倍体小偃麦的根尖细胞染色体数目为2n=56，花粉母细胞减数分裂中期Ⅱ染色体构型为2n=28Ⅱ，具有高度的细胞学稳定性。

The extra divisions or fusions appearedonly in some flower buds of one plant, some anthers in the same buds, or even inindividual cells of tetrads.

六倍体Ⅲ和诸葛菜杂种的一个单株中，减数分裂粗线期之前未见异常，粗线期之后，染色体缺少配对的过程，单价体聚集在一起。

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。
