着丝点是染色体的主缢痕,在这个地方姐妹染色单体连在一起。
Centromere is the primary constriction on the chromosome, a region at which the sister chromatids are held together.
染色体数目、相对长度和着丝点位置均无明显区别。
No difference was observed in chromosomal number, relative length and chiasma location.
易位的紧穗野生稻片段都很小,主要分布在远离着丝点的区域。
The incorporated O. eichingeri segments were small in size and mainly distributed away from centromeres.
图表中出现的结果包括每条染色体的相对长度、臂比、着丝点指数。
Table is presented listing the results obtained including the relative length, arm ratio and centromere index of each chromosome.
有证据表明,这些片段可能代表羚牛染色体着丝点的卫星DNA单体。
It also suggests that these BamHI fragments may represent repeat units of the centromeric satellite DNA of takin.
首次发现黑麦染色体的核仁组成中心区、着丝点和端粒均能用硝酸银染色。
It was found that NORs, kinetochores and telomeres could all be stained by silver nitrate.
着丝点是一个大分子物质,位于染色体的着丝粒上,在有丝分裂期间,是纺锤体微管附着的位置。
The kinetochores are the macromolecular structure that is associated with the centromeres of chromosomes and serves as the site of spindle microtubule attachment during mitosis.
结果表明,常染色体联会复合体的相对长度和着丝点指数与体细胞染色体的相应参数具有很好的吻合性。
It is shown that the mean relative lengths and centromeric indices of autosomal SCs agree closely with those of mitotic chromosomes.
由此她认为,染色体末端的一个结构防碍了染色体的变化,她把这个结构叫作“端粒”(在染色体端位上的着丝点)。
This led her to believe that a structure at the end of the chromosome prevents chromosomes from changing. She called this structure the telomere.
