Abstract
DNA segregation ensures that cell offspring receive at least one copy of each DNA molecule, or replicon, after their replication. This important cellular process includes different phases leading to the physical separation of the replicons and their movement toward the future daughter cells. Here, we review these phases and processes in enterobacteria with emphasis on the molecular mechanisms at play and their controls.
摘要
DNA 分离确保细胞后代在 DNA 分子（即复制子）复制后至少获得每个分子的一个拷贝。这一重要的细胞过程包括不同阶段，最终导致复制子的物理分离并向未来的子细胞移动。在这里，我们综述肠道细菌中的这些阶段和过程，重点关注其中起作用的分子机制及其调控。
