染色体

Abstract］ Objective To study and find a simple and pragmatic method for chromosome preparation and banding.

目的 寻找简单实用的高分辨染色体制备及显带方法。

Its research progress stages are divided into two parts: chromosome morphological mark analysis and banding analysis.

这个项目的研究发展阶段可分成两部分：染色体形态学上的标记分析阶段和条带分析阶段。

The researches on chromosome shape, structure, and banding pattern are foundation of gene mapping research.

研究染色体的形态、结构，尤其是带型，是基因定位与基因图谱研究的基础工作。

Phragmoplast A barrel-shaped body appearing in dividing plant cells during late anaphase and telophase between the two separating groups of chromosomes.

成膜体：指在分裂的植物细胞中，分裂后期和末期时两组正在分开的染色体之间形成的桶状结构。

The last step is to construct a physical map of the base sequence of the chromosomal DNA.

最后就是要构建染色体 DNA 碱基顺序的物理图谱。

He sought the view of Family Tree DNA of Houston, only to learn last week from its president, Bennett Greenspan, that he belonged to a different branch of the Y chromosome family tree from that of the Mongol emperor, and could not be descended from him.

这次他改委托休斯敦的"族谱DNA"公司进行检测，并在上周得知结果。该公司总裁葛林斯班亲自告诉他，他的Y染色体族谱与成吉思汗属于不同的分支，因此不可能是这位蒙古大帝的后裔。

Objective To investigate the circumstances of gene deletion of Chinese patients with Duchnne's type muscular dys-trophy（DMD and Becher muscular dystrophy.

Duchenne和Becker型肌营养不良症是我国最常见的与X染色体连锁的隐性遗传性疾病，发病率约1/3300活男婴［1］。该病系肌营养不良蛋白基因突变所致［2，8］。

Furthermore, chromosome evolution and biogeography of Apioideae were discussed:(1) Cytology : Karyological studies on seven genera, i.e.

并在已有资料的基础上，对芹亚科的染色体演化模式以及生物地理学问题进行了初步的总结和讨论。

The biological analysis results showed: Population Doubling Time of cells was approximately 24 h;Diploid account for 76%～88% in cell's chromosome;By Isozyme analysis of Lactic Dehydrogenase,Malic Dehydrogenase,cross contamination had not taken place;The test results of ...

结果表明：细胞群体倍增时间约为24 h；细胞染色体中二倍体(2n=60)占主体，镜检细胞的百分比为98.2%；乳酸脱氢酶、苹果酸脱氢酶同工酶分析，没有其他物种污染；细菌、真菌、病毒、支原体检测阴性。

After matching each pair of homologous chromosomes that bivalent.

配对后的每对同源染色体称二价体。

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.

要是在劳改农场，你等着挨绳子吧！
