Bivalents
常見例句
- When synapsis is complete the paired chromosomes are referred to as bivalents.
當(dāng)聯(lián)會完成的時候,那配成對的染色體叫做二價體。 - The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
有時交叉可以從二價體末端處滑開,因此移端過程可以降低交叉頻率。 - There were less bivalents at meiotic MI of PMC than expected,and no multivalent had been found.
在小孢子發(fā)育過程中,四分體期有多個微核出現(xiàn),同時發(fā)生了高頻的多分孢子,形成五分、六分孢子; - Synapsis (pairing) The association of homologous chromosomes during the prophase stage of meiosis that leads to the production of a haploid number of bivalents.
聯(lián)會(配對):能產(chǎn)生單倍二價體的減數(shù)分裂前期,同源染色體的聯(lián)合現(xiàn)象。 - Abstract:We have developed a technique of random-primed tritium labeled DNA extension on the pachytene bivalents of rice-field eels.
采用隨機(jī)引物,在黃鱔二價體上建立了氚標(biāo)記引物原位DNA合成技術(shù),并詳細(xì)探索了該技術(shù)的實驗條件。 - Zygotene is characterized by the active and specific pairing(synapsis) of homologous chromosomes leading to the formation of a haploid number of bivalents.
偶線期時,以同源染色體活躍的、特定的配對(聯(lián)會)為特征,形成了單倍數(shù)的二價染色體。 返回 Bivalents
