常見(jiàn)例句

• When synapsis is complete the paired chromosomes are referred to as bivalents.
  當(dāng)聯(lián)會(huì)完成的時(shí)候,那配成對(duì)的染色體叫做二價(jià)體。
• The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
  有時(shí)交叉可以從二價(jià)體末端處滑開(kāi)，因此移端過(guò)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(guò)程中，四分體期有多個(gè)微核出現(xiàn)，同時(shí)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(huì)（配對(duì)）：能產(chǎn)生單倍二價(jià)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(jià)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(shí)驗(yàn)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(shí)，以同源染色體活躍的、特定的配對(duì)（聯(lián)會(huì)）為特征，形成了單倍數(shù)的二價(jià)染色體。
