The partitioning apparatus of your mitotic-like cell cycle the cells utilised to copy independently would then pull Every single list of chromosomes to at least one side with the mobile, nonetheless certain by centromeres. These centromeres would prevent their replication in subsequent division, resulting in four daughter cells with just one duplicate of one of many two a$$ initial pox-like viruses. The procedure resulting from combination of two related pox viruses in the same host closely mimics meiosis.[83]
