Binary fission in bacteria is a process by which one bacterial cell divides into two identical daughter cells. This can be modeled in two stages:
1. Replication: The first stage involves the replication of the bacterial DNA. The DNA molecule in the bacterial cell replicates, creating two identical copies.
2. Cell Division: In the second stage, the bacterial cell undergoes division. The cell membrane and cell wall constrict in the middle of the cell, leading to the separation of the two DNA copies into two distinct daughter cells.
So, the correct answer would be "two stages."
