英英释义
Noun
- the second stage of the prophase of meiosis
例句
- Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis. 前期可被分为连续的阶段：细线期、偶线期、粗线期、双线期和终变期。
- In addition,the homeologous multivalent s have been observed in spreads of zygotene but these multivalents were ultimate ly resolved. 在偶 线期还观察到由同祖配对形成的多价体，但在随后阶段中这些多价体消失。
- Further examinations revealed the gold particles representing actin in SCs of autosomes and sex chromosomes and also in SCs of zygotene and pachytene. 观察到，常染色体SC和性染色体SC以及偶线期和粗线期SC中都含有肌动蛋白，肌动蛋白分布于SC的端部和侧生组分上，代表肌动蛋白的胶体金颗粒在SC上往往成簇存在。
- The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study, which would help the studies of meiosis and molecular cytogenetics in lotus. 摘要本研究建立了中国莲偶线期染色体的核型，为研究莲的减数分裂过程及分子细胞遗传学研究提供基础。
- The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study,which would help the studies of meiosis and molecular cytogenetics in lotus. 本研究建立了中国莲偶线期染色体的核型,为研究莲的减数分裂过程及分子细胞遗传学研究提供基础。
- Zygotene is characterized by the active and specific pairing(synapsis) of homologous chromosomes leading to the formation of a haploid number of bivalents. 偶线期时，以同源染色体活跃的、特定的配对（联会）为特征，形成了单倍数的二价染色体。
