Binary fission in a prokaryote
1. The bacterium before binary fission is when the DNA is tightly coiled.
2. The DNA of the bacterium has replicated.
3. The DNA is pulled to the separate poles of the bacterium as it increases size to prepare for splitting.
4. The growth of a new cell wall begins to separate the bacterium.
5. The new cell wall fully develops, resulting in the complete split of the bacterium.
6. The new daughter cells have tightly coiled DNA, ribosomes, and plasmids.

Binary fission ("division in half") is a kind of asexual reproduction. It is the most common form of reproduction in prokaryotes and occurs in some single-celled eukaryotes.

After replicating its genetic material, the cell divides into two nearly equal sized daughter cells. The genetic material is also equally split. The daughter cells are genetically identical (unless a mutation occurs during replication).

Some biologists use this term for multi-cellular organisms that asexually reproduce by dividing into two (e.g., some starfish). This is also known as 'fragmentation'. Bacteria uses binary fission to reproduce quickly. They have other methods for exchanging DNA with each other.

During binary fission, the DNA molecule divides and forms two DNA molecules. Each molecule moves towards the opposite side of the bacterium. At the same time, the cell membrane divides to form 2 daughter cells. In the process of cell division (in eukaryotes), first the division of nucleus takes place after which the division of cytoplasm (cytokinesis) takes place. After division, the new cells will grow and the process repeats itself.
