The FtsZ Ring
Captions available
The idea
The FtsZ ring is a ring of repeating FtsZ protein units forming at a bacterium's midpoint, directing formation of a septum, the wall separating daughter nucleoids.
In practice
Once the replicated chromosomes clear the midpoint, the FtsZ ring recruits wall material to build the septum inward.
Where people slip
The septum grows inward from the edge toward the center — opposite a plant cell's cell plate.
