减数分裂的

Although the oocytes collected from ovaries before IVM are usually arrested at the diplotene stage, they are different in developmental competence.

用于IVM的卵母细胞虽然都停滞在第一次减数分裂的双线期，但质量是不同的，造成卵母细胞体外成熟结果有很大差异。

The first stage of meiosis, constituted by a series of events that include ''.

前期阶减数分裂的第一个阶段，由一系列的事件组成，包括脱氧核糖核酸的''。

In sexually reproducing organisms like us, a process called meiosis halves this number.

在象我们这样的有性生殖生物体中，称为减数分裂的过程平分了它的数目。

Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。

2PKC inhibitor—staurosporine or sphingosine could also inhibitthe stimulatory effect of FSH(100IU/L);while PKC activator,phorbol myristate acetate,at the concentration of 10-8-10-5M had a dual effect on the meiotic resumption of pig CEO.

2PKC的抑制剂——Staurosporine(10-9-10-6M)或Sphingosine(10-8-10-5M)也能够显著抑制FSH(100IU/L)的刺激作用；然而PKC的激活剂——PMA(10-8-10-5M)对猪CEO减数分裂的恢复具有双相作用。

The first stage of meiosis, constituted by a series of events that include DNA replication, the synapsis of homologous chromosomes, crossing over, the formation of chiasmata, and contraction of the chromosomes.

前期阶减数分裂的第一个阶段，由一系列的事件组成，包括脱氧核糖核酸的复制，同种染色体结合、交叉，染色体形成以及染色体的收缩一套，一系列

In synapsis Red1, Hop1 and Zip1 are the components of synaptonemal complex. Hop2 is required for synapsis.

Red1、Hop1和Zip1是联会复合体的组成成分，而联会也要求其他减数分裂的特异性基因如Hop2的参与。

The first stage of meiosis ,constituted by a series of events that include DNA replication,the synapsis of homologous chromosomes,crossing over,the formation of chiasmata,and contraction of the chromosomes.

前期阶减数分裂的第一个阶段，由一系列的事件组成，包括脱氧核糖核酸的复制，同种染色体结合、交叉，染色体形成以及染色体的收缩

Chiasmata also help to hold homologs together until the start of anaphase, thus helping to ensure the correct distribution of chromosomes into the daughter nuclei.

交叉还可以使同源染色体始终在一起直到细胞减数分裂的后期，这样确保了染色体可以正确的进入子细胞。

Thus, the meiotic chromosome cofigurations showed that the tetraploids and hexaploids in C.reticulata allopolyploids, and the appearance of a few tetravalents in some populations might indicatehomology of chromosomes in different genomes to some extent.

根据减数分裂的构型，我们认为，四倍体和六倍体分别为异源四倍体和异源六倍体，少数四价体的存在表明染色体有部分同源性。

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。
