New cards
Prokaryotes cell division
They divide by binary fission (asexual reproduction of cells).
2
New cards

1. binary fission
Replication of the circular prokaryotic chromosome beings at the origin of replication and continues in both directions at once.
3
New cards

2. binary fission
The cell begins to elongate. FtsZ proteins migrate towards the midpoint of the cell.
4
New cards

3. binary fission
The duplicated chromosomes move away to opposite ends of the cell. Ftsz proteins form a ring around the periphery of the midpoint between the chromosomes.
5
New cards

4. binary fission
The FtsZ ring directs the formation of a septum that divides the cell. Plasma membrane and cell wall materials accumulate.
6
New cards

5. binary fission
After the septum is complete, the cell pinches in two, forming two daughter cells. FtsZ is dispersed throughout the cytoplasm of the new cells.
