Binary fission

Binary Fission

Binary fission (pronunciation: /ˈbaɪnəri fɪʃən/) is a type of asexual reproduction and cell division used by all prokaryotic organisms, and some eukaryotic organisms such as amoeba and paramecium. The term originates from the Latin words binarius meaning "double" and fissio meaning "splitting".

Process

Binary fission involves the division of a single entity into two parts, which then become separate entities. The process begins when the DNA of the cell is replicated. The replicated DNA strands are then separated, and a new cell membrane starts to form in the middle of the cell. The cell then splits into two, each with identical DNA.

Types of Binary Fission

There are three types of binary fission: transverse, longitudinal, and oblique.

• Transverse Fission: This is the most common type of binary fission where the cell divides perpendicular to the long axis.
• Longitudinal Fission: In this type, the cell divides along its long axis.
• Oblique Fission: This is a rare type of binary fission where the cell divides at an angle other than 90 or 180 degrees.

Advantages and Disadvantages

Binary fission allows for rapid population growth and is less complex than other forms of reproduction. However, it does not provide genetic variation, which can be a disadvantage in changing environments.
