Study Notes
Asexual Reproduction: Binary Fission
Definition
- Binary fission is a type of asexual reproduction in which a single cell divides into two identical daughter cells.
Characteristics
- Occurs in prokaryotic cells, such as bacteria
- No genetic variation is introduced during the process
- Results in two genetically identical daughter cells
Process
- Replication of DNA: The cell's DNA is replicated, resulting in two identical copies.
- Cell Elongation: The cell grows and elongates, preparing for division.
- Cytokinesis: The cell divides into two daughter cells, each receiving a copy of the DNA.
- Separation: The daughter cells separate, resulting in two identical cells.
Examples
- Bacteria, such as E. coli, reproduce through binary fission
- Some protists, such as amoebas, also reproduce through binary fission
Advantages
- Rapid reproduction: allows for quick population growth
- Genetic consistency: ensures that the genetic traits of the parent cell are preserved
Disadvantages
- Lack of genetic variation: can make the population more susceptible to diseases and environmental changes
