Packaged within geminate particles, the genomes of geminiviruses are single-stranded circular DNAs that are replicated mainly by a rolling circle mechanism, characteristic to prokaryotes. Previous researches have indicated that geminiviruses can generate various DNA replication forms in bacteria, suggesting that geminiviruses possess the potential to regulate the expression of certain viral genes in prokaryotic systems.

双生病毒在植物细胞中是主要以原核生物形式的rolling circle replication方式做复制，而先前研究指出双生病毒可以在原核系统里进行复制，因此，双生病毒基因体中应具有在原核系统中亦能表现的调控机制，除了已知的基因外，是否有其他未知的基因参与这项机制仍不清楚。

prokaryotic：原核生物

我们人类只是适应居住在这一个原核生物(prokaryotic)世界的一个有机体, 而我们人类的动力正来自这些原核生物. 若我们检查化石形成的条件, 似乎细菌类都不会形成化石, 因为它们没有坚硬的外壳或构造. 但是蓝绿藻却是目前地球上已知的最古老化石之一,

prokaryote 原核生物 | prokaryotic 原核(生物)的 | prokaryotic cell 原核细胞

female pronucleus：雌原核

它由从中心粒发射的微丝引导,向雌原核(female pronucleus)方向迁移. 在哺乳动物中,雌原核在与雄原核融合前首先必须完成第二次减数分裂. 第二极体的排出是减数分裂完成的标志. 随着雌、雄原核相遇和融合,受精结束. 紧接着第一次卵裂开始.

male pronucleus：雄[性]原核

精子的细胞核膜解体形成小的囊泡,并立即与精子细胞核脱离,形式没有核被膜的精子染色质,但很快形成新的核被膜,此时称为雄性原核(male pronucleus). 雄性原核向卵细胞的雌性原核移动,这种迁移是由精细胞的中心粒产生的微管指导的,

male pronucleus：雄原核

精核直接进入卵子中,然后解聚集,称为雄原核(male pronucleus). 它由从中心粒发射的微丝引导,向雌原核(female pronucleus)方向迁移. 在哺乳动物中,雌原核在与雄原核融合前首先必须完成第二次减数分裂. 第二极体的排出是减数分裂完成的标志.
