中期分裂

Divide, and each sister chromatid moves to one of the poles of the spindle.

第二次核分裂开始于分裂中期，子细胞中染色体重新排列在赤道板上。

While under natural low temperature (10-20℃), a great deal of abnormalities, including micro nucleoli, scattered and lagged chromosomes and anaphase bridges were detected during PMC meiosis, even though the abnormalities were different between the two cultivars; the ratio of micro nucleoli was 22.88% of average, which was obviously higher than that of control (4.56% of average under normal temperature); and the ratios of univalent and multivalent in diplotene, which increased seriously, were 8.82% and 17.65% of Tainong 1, and 14.52% and 24.19% of Irwin under natural low temperatures.

低温（10~20℃）条件下，减数分裂过程中核仁的行为发生大量异常，微核仁的平均检出率高达22.88%，明显高于常温条件下的平均4.56%；双线期单价体和多价体的发生频率有明显增加，其中台农1号为8.82%和17.65%，Irwin为14.52%和24.19%；减数分裂中期Ⅰ、Ⅱ及后期Ⅰ、Ⅱ均观察到落后染色体，其中台农1号异常率为12.73%、5.63%、15.79%和4.76%，Irwin为11.11%、7.61%、9.52和6.38%。

The results of the karyotype analysis indicated that the heteromorphic sex chromosomes existed in mitotic prometaphase chromosomes of the early embryos. Zchromosorne was the longest among the total of 56 chromosomes, and usually had twoconstricts at the ...

经对23个分散好、完整的分裂相的分析表明：家蚕早期胚胎有丝分裂早中期染色体中有异型性染色体存在，Z染色体是核型中最长的，通常具有亚端和亚中部次缢痕，W染色体很短，约相当干Z染色体的1／3长。

The action of SOSP-9607 on AS-ODN and the cell division was blocked in metaphase and inducer cell apoptosis.

SOSP-9607在AS-ODN作用下，细胞分裂阻滞在分裂期的中期，并诱导细胞发生凋亡。

Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

And the research materials were often meiotic pachytene chromosomes of sex gland and mitotic prometaphase of early embryos and diapause eggs\' somatic cells.

早期，家蚕染色体识别和基因定位研究主要利用性腺减数分裂粗线期的染色体、早期胚胎和滞育卵有丝分裂早中期的染色体作为材料，按照相对长度和部分限性易位系统或缺失等来进行核型分析。

In metaphase, Septin 1 is situated in equatorial plate. In anaphase, it is located in centrosome and in telophase, it is in post-mitosis bridge. The mutation of phosphorylation sites does not affect the location of Septin 1 itself and Aurora-B.

在有丝分裂中期位于赤道板，后期位于中间体及末期的后有丝分裂桥，磷酸化位点的突变没有影响自身和Aik2的定位。

The localization of 〓 changed during the process of rat oocytes maturation. In GV stage oocytes,〓 was concentrated in GV but it concentrated around chromosomes from metaphase Ⅰ to telophase Ⅰ.

〓的在大鼠卵母细胞内的定位随成熟分裂的过程而变化：在GV期生发泡内核仁周围有特异分布，在成熟分裂的中期至末期〓在染色体周围区域有特异分布。

In the BC〓F〓 and BC〓F〓 generation of Yannong15×Thinopyron intermedium hybrid, 4 octoploids which had chromosome number of 2n=56 and could form 28 bivalent at PMC MI, 14 disomic addition lines which had chromosome number of 2n=44 and could form 22 bivalent at PMC MI; three monosomic addition lines which had chromosome number 2n=43 and had the chromosome configuration of 21Ⅱ+1Ⅰ at PMC MI, 1 substitution line which had chromosome number 2n=42 and could form 21 bivalent at PMC MI were selected by observation of mitosis in root tip cell and meiosis in pollen mother cell.

在烟农15与中间偃麦草杂交的BC〓F〓和BC〓F〓代中，通过根尖有丝分裂和花粉母细胞减数分裂中期Ⅰ观察选出4个2n=56，PMC MI染色体构型为28Ⅱ的八倍体小偃麦；14个2n=44，PMC MI染色体构型为22Ⅱ的双体异附加系；3个2n=43，PMC MI染色体构型为21Ⅱ+1Ⅰ的单体异附加系；1个2n=42，PMC MI染色体构型为21Ⅱ的异代换系。

Methods Cell cultures were harvested and stained with haematoxylin and eosin,to analyze cellular metaphase morphology.

收获细胞经苏木素和伊红染色，观察分裂中期细胞核形态，计算核极分裂象细胞百分比。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
