In scc-3 mutant animals, normal SCs were not visible and ～24 DAPI-staining positive structures were seen in diakinesis, indicating that SCC-3 is necessary for the establishment or maintenance of sister-chromatid cohesion.

在scc-3突变型线虫细胞中，无法观察到正常的联会复合体，且在终变期出现大约24个DAPI染色阳性信号。

Diplotene chromosome to further reduce this time synaptonemal complex has disappeared.

双线期的染色体进一步缩短，此时联会复合体已消失。

We has discussed the mechanism of the trivalent synaptic adjustment,and it's important use to control the chiasmata and disjunction of the chromosomes.

This study provides genetic evidence that SUN1-telomere interaction is essential for telomere dynamic movement and is required for efficient homologous chromosome pairing/synapsis during mammalian gametogenesis.

我们的研究首次从遗传学上证明了SUN1蛋白和端粒的相互作用对于端粒在动物生殖细胞减数分裂中的动态变化，高效的同源染色体配对、联会以及哺乳动物的配子发生是必不可少的。

The other type was somatic meiosis which was analogous to that existed in the process of gametogenesis, and characterized by the pairing and synapsis of homologues chromosomes.

另一种类型是体细胞减数分裂，这种类型类似于大小孢子发生过程的减数分裂，如第一次分裂前期也有染色体的联会和配对。

Genes important for male gametogenesis involved in highly con-served landmark events such as meiotic recombination, formation of the synaptonemal complex, sister chromatid cohesion, spermiogenesis during postmeiotic stages, and checkpoints and factors required for the meiotic cell cycle .

精子发生中的重要基因与一系列精子发生过程中阶段性的细胞事件密切相关，例如减数分裂重组、联会丝复合物的形成、姊妹染色体的结合、减数分裂后精子的变态以及减数分裂周期中的关键点和必需因子等。

In 1976, the International Astronomical Union revised the definition of the AU for greater precision, defining it as that length for which the Gaussian gravitational constant takes the value 0.01720209895 when the units of measurement are the astronomical units of length, mass and time.

但实际上地球绕日的轨道不是一个圆形，而是一个椭圆形：最初天文单位的定义就是上述椭圆的半长轴的长度。1976年，国际天文学联会把一天文单位定义为一颗质量可忽略、公转轨道不受干扰而且公转周期为365.2568983日的粒子与一个质量相等约一个太阳的物体的距离。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
