Their DNA is usually located in a specific part of the cell, called the nucleoid. 它们的遗传物质DNA通常位于一个特定的部位，为了与真核细胞典型的核有所区别，我们称它为核区或类核。
The results showed that the RLO with an integrated cell membrane and a nucleoid of low electronic density appeared in the cytoplasm . 研究表明，该病原体具有完整的细胞包膜,内部具有低电子密度拟核，在胞浆中以两种类型存在-繁殖型和静止型；
