问题是,虽然胞内同生在真核生物中非常常见,这往往造成吞噬其他细胞,但是在较为硬质的细菌难以察觉。
The trouble is that, while cells within cells are common in eukaryotes, which often engulf other cells, they're vanishingly rare in more rigid bacteria.
虽然,像细菌一样,古生菌也没有细胞核,但是它们与你我这样的真核生物具有其他共同的特性。
While, like bacteria, archaeans don't have a cell nucleus, they share other traits with eukaryotes like you and me.
这种病毒可能具有某种独特的结构,这种结构是能够影响细菌与真核生物的病毒所不具有的——它不得不像其感染的生物体一样,能够在同样极端的环境中生存。
This virus may have a unique structure not found in viruses affecting bacteria and eukaryotes-it has to be able to survive in the same extreme environment as the organism it infects.
