Binary fission

Definition

Binary fission is a form of asexual reproduction in which a single microbial cell divides into two genetically identical daughter cells. It is the primary method of reproduction for prokaryotic organisms such as bacteria.

5 Must Know Facts For Your Next Test

1. Binary fission begins with the replication of the organism's DNA.
2. The process involves elongation of the cell, followed by division at the mid-point.
3. Binary fission results in two daughter cells that are clones of the parent cell.
4. Environmental factors such as nutrient availability and temperature can influence the rate of binary fission.
5. Binary fission does not involve genetic recombination, leading to low genetic diversity among progeny.
