State
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.
Show
Once the replicated chromosomes clear the midpoint, the FtsZ ring recruits wall material to build the septum inward.
Watch for
The septum grows inward from the edge toward the center — opposite a plant cell's cell plate.
