基本英英例句例句
染色单体¹⁰⁰原型chromatid的复数
名词 chromatid:
one of two identical strands into which a chromosome splits during mitosisDuring mitosis, sisterchromatidsremain joined by their centromere until anaphase.在有丝分裂期间，姐妹染色单体在分裂后期之前都是通过着丝点连接的。
Each chromosome consists of twochromatidsheld together by the centromere.每个染色体由两个染色单体所组成，它们被一个着丝点联结在一起。 The granules were broken down and relaxed coils appeared at end of threadlike chromosome and showed two chromatids.
在有的线状染色体末端可以见到松开的相关螺旋，显示出两条染色单体。 cnki
Cell proliferation depends on the duplication of chromosomes followed by the segregation of sister chromatids to opposite poles of the cell prior to cell division.
细胞增殖依赖于细胞分裂前染色体的复制及随后的姐妹染色单体分离到达两极。 cnki
In mitotic anaphase, sister chromatids split at their centromeres and are pulled apart toward opposite poles.
在有丝后期，姐妹染色单体由于着丝点的分裂而分开并且被拉向细胞的两极。 sunbb
In normal cells, cohesin can connect sister chromatids only in S phase, even though newly synthesized cohesin complexes can associate with DNA in the subsequent G phase5, 6.
在正常细胞中，内聚力只在细胞分裂的 S期联合染色体，尽管新合成的内聚力联合体能在 G期联合 DNA5，6。 kekenet
Often this intertwining leads the chromatids of homologous chromosomes to actually exchange corresponding pieces of DNA, a process called crossing- over or genetic reassortment.
缠绕经常导致同源染色体内部的非姐妹染色单体会交换 DNA的部分片段，这个过程叫交叉互换或者是基因重组。 sunbb
Spindle The spindle-shaped structure formed in the cytoplasm during MITOSIS and MEIOSIS that is responsible for moving the chromatids and chromosomes to opposite poles of the cell.
是细胞有丝分裂或减数分裂中胞质内形成的纺锤样结构，负责将染色体或染色单体拉向细胞两极。 plb.snnu.edu.cn |
