1. Replication of DNA: The bacterium's single circular chromosome replicates, creating two identical copies.
2. Cell Growth: The cell grows in size and elongates.
3. Separation: The two copies of the chromosome move to opposite ends of the cell, and the cell membrane and cell wall begin to grow inward.
4. Division: The cell completely divides, forming two identical daughter cells.
Each new bacterium is a clone of the original, carrying the same genetic information.
