Generalized transduction vs Specialized Transduction
Shomu's Biology・8 minutes read
Bacteria share genetic content through transduction using viruses in horizontal gene transfer. Generalized transduction transfers pure bacterial DNA while specialized transduction transfers a small portion of bacterial DNA along with the viral genome.
Insights
- Generalized transduction transfers complete bacterial DNA between bacteria using bacteriophages, while specialized transduction transfers a smaller portion of bacterial DNA along with the viral genome.
- Generalized transduction involves the packaging and transfer of pure bacterial DNA by bacteriophages, while specialized transduction integrates viral DNA with bacterial DNA, leading to the transfer of a specific portion of bacterial DNA.

Recent questions
What is transduction in bacteria?
Transduction in bacteria is the process where genetic material is transferred between bacterial cells using viruses called bacteriophages.
What is the difference between generalized and specialized transduction?
Generalized transduction transfers pure bacterial DNA using bacteriophages, while specialized transduction transfers a small portion of bacterial DNA along with the viral genome.
How does generalized transduction occur?
In generalized transduction, bacteriophages infect a bacteria, replicate, package bacterial DNA, and transfer it to another bacteria.
How does specialized transduction differ from generalized transduction?
Specialized transduction involves lysogenic bacteriophages integrating their DNA with bacterial DNA, leading to the transfer of a portion of bacterial DNA to another bacteria.
What is the role of bacteriophages in transduction?
Bacteriophages play a crucial role in transduction by infecting bacteria, replicating, and transferring bacterial DNA from one bacterium to another, either in pure form (generalized transduction) or along with viral DNA (specialized transduction).

Bacterial gene transfer via transduction explained.
- Transduction is the process through which bacteria share genetic content using viruses, known as horizontal gene transfer.
- Generalized transduction involves the transfer of pure bacterial DNA from one bacteria to another using bacteriophages.
- Specialized transduction, on the other hand, transfers a small portion of bacterial DNA along with the viral genome.
- In generalized transduction, bacteriophages infect a bacteria, replicate, package bacterial DNA, and transfer it to another bacteria.
- Specialized transduction starts similarly but involves lysogenic bacteriophages integrating their DNA with bacterial DNA, leading to the transfer of a portion of bacterial DNA to another bacteria.
