This document summarizes different types of asexual and sexual reproduction in bacteria. The main types of asexual reproduction discussed are budding, fragmentation, and binary fission. Binary fission involves the bacterial DNA replicating and the cell membrane dividing the original cell into two identical daughter cells. Sexual reproduction in bacteria can occur through conjugation, transformation, or transduction, which involves the transfer of genes between bacteria through direct contact, uptake of extracellular DNA, or bacteriophage transmission, respectively.
Reproduction methods in bacteria
- 1. WELCOM E
- 3. Type of Asexual reproduction in bacteria : Budding Fragmentation Binary Fission
- 4. Budding:In this case small bud farmation from a parental cell. And daughter cell , finally gets separated from the parent cell.
- 5. FRAGMENTATION: This is a form of reproduction where a new organism grows from a fragment of parent cell. Each fragment develops into in a fully grown individual.
- 7. Binary Fission – It is division of a single cell into two or more cells,and the regeneration of those cells into separate entities resembling the original cell.
- 8. single DNA molecule replicates and both copies attach to the cell membrane. The cell membrane begins to grow between the two DNA molecules
- 9. the cell membrane begins to pinch inward; cell wall then forms between the two DNA molecules dividing the original cell into two identical daughter cell
- 10. BINARY FISSION
- 11. SEXUALREPRODUCTION Many plasmids can insert into the DNA of the nucleus, and detach from it. In doing so, the plasmid may leave part of the plasmid DNA behind, and take some of the nuclear DNA with it.
- 12. SEXUALREPRODUCTION plasmids can transfer from cell to cell. The cells need not be of the same bacterial 'species'.
- 13. SEXUAL REPRODUCTION: Conjugation Transformation Transduction
- 14. CONJUGATION one bacterium connects itself to another through a protein tube structure called a PILUS. Genes are transferred from one bacterium to the other through this tube.
- 16. TRANSFORMATION The bacterium binds the DNA and transports it across the bacterial cell membrane. The new DNA is then incorporated into the bacterial cell's DNA.
- 18. TRANSDUCTION involves the exchanging of bacterial DNA through bacteriophages.
- 20. BACTERIOPHAGES viruses that infect bacteria. There are two types of transduction: generalized and specialized transduction.
