Most
prokaryotes reproduce asexually through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical cells.
- Binary fission begins with the single DNA molecule replicating and both copies attaching to the cell membrane.
- Next, the cell membrane begins to grow between the two DNA molecules. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward.
- A cell wall then forms between the two DNA molecules dividing the original cell into two identical daughter cells.
