Q:

Bacteria divide by

A) Binary Fusion B) Cytokinesis
C) Binary Fission D) Both B & C
 
Answer & Explanation Answer: C) Binary Fission

Explanation:

Most bacteria divide by binary fission, a form of cell division in which DNA replication and segregation occur simultaneously. This process involves active partitioning of the single bacterial chromosome and positioning of the site of septation.

 

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells.

 

Binary fission begins when the DNA of the bacterium divides into two replicates. The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell.
