In model organism fission yeast,Schizosaccharomyces pombe,100-200 rDNA gene copies are located on both left and right ends of chromosomeⅢ.The integrity of rDNA is critical for cell growth and survival.

在模式生物裂殖酵母(fission yeast，Schizosaccharomyces pombe)基因组中，100-200拷贝的rDNA基因分布在Ⅲ号染色体左右两端的末端附近。rDNA区的完整性对于细胞生长和存活是至关重要的。

Background and Objective Pseudohypertrophic muscular dystrophy is a kind of lethal X-chain recessive inherited disease. The etiological factor is mainly due to gene mutation of Xp21 which induce the structural and functional abnormality of a kind of cell skeleton protein: dystrophin.

背景和目的假肥大型肌营养不良症(pseudohypertrophic muscular dystrophy，PMD)是一种常见的致死性X-连锁隐性遗传病，病因主要是由于X染色体短臂2区1带(Xp21)的基因突变而导致一种细胞骨架蛋白——抗肌萎缩蛋白的结构和功能异常所致。

The identified proteins are involved in a variety of cellular process including several zinc finger proteins relevant to transcription regulation, such as zinc finger 198, 263, 14, 224, zf6, novel protein similar to transcriptional represser CTCF, and kruppel-like zinc finger protein; two members of the ADAMs (a disintegrin and metalloprotease domain) family; two members of integrin family; several proteins involved in the signal transduction, cell-cycle control, chromatin remodeling and transcription repression; and also some proteins of cell skeleton and some with unknown functions.

鉴定出 的蛋白包括多个与转录调控相关的锌指蛋白，如锌指蛋白198、263、14、224、zf6、转录抑制因子cTcF样蛋白、幻肚pple样锌指蛋白等：两个含金属蛋白酶结构域和整合素结合结构域的家族成员ADAM28和ADAM17；两个整合素家族成员pZ整合素和含十个EGF样结构域的整合素；与细胞信号转导通路有关的蛋白；与细胞周期调控有关的蛋白；与染色体重塑和基因转录抑制有关的蛋白；细胞骨架蛋白以及其他功能未明的蛋白等。

Not all polyploids are reproductively isolated from their parental plants, so an increase in chromosome number may not result in the complete cessation of gene flow between the incipient polyploids and their parental diploids.

并非所有的多倍体与其亲本有生殖隔离，因此，染色体数目增加不会导致初始多倍体与其二倍体亲本之间的基因交流完全停止。

Genes （between 60,000 and 100,000 in humans） are carried by the chromosomes （rodlike structures in the cell nuclei） and mitochondria （circular structures in cell cytoplasm present in multiple copies）.

基因（人类有6万~10万条）由染色体和线粒体（存在于细胞质中的多个环形结构）携带。

Genes （between 60,000 and 100,000 in huma ） are carried by the chromosomes （rodlike structures in the cell nuclei） and mitochondria （circular structures in cell cytoplasm present in multiple copies）.

基因（人类有6万~10万条）由染色体和线粒体（存在于细胞质中的多个环形结构）携带。

Lr45 was a resistant gene against wheat leaf rust disease originated from Secale cereale and was localized onto the chromosome 2A.

小麦抗叶锈病基因Lr45发现于一个日本小麦与黑麦的杂交后代中，并定位于2A染色体上。

The expression of specific genes in sex chromosomes is the basis of sexspecific membrane protein in mammalian spermatozoa.

在精子形成过程中，存在性染色体特异基因的表达，这是X、Y精子膜蛋白差异形成的基础。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
