What is the method called by which bacteria reproduce, involving the splitting of one cell into two?

• A. Binary Fission
• B. Mitotic Division
• C. Fission
• D. Cell Division

Answer: (C)

The method by which bacteria reproduce through the splitting of one cell into two is known as binary fission. This is a form of asexual reproduction where a single bacterial cell divides into two identical daughter cells, each containing a copy of the original cell’s DNA. The process begins with the replication of the bacterial chromosome, followed by elongation of the cell and ultimately, the formation of a septum that divides the cell into two separate entities.

While the term "fission" can refer to the splitting of a cell, it does not specifically denote the bacterial reproduction process as precisely as binary fission does. Mitotic division, on the other hand, is a process that occurs in eukaryotic cells, not bacteria, and involves a more complex series of steps including mitosis and cytokinesis. Cell division is a general term that could apply to various types of reproduction including binary fission, but it lacks the specificity that binary fission provides in the context of bacterial reproduction.
