Bacterial transduction is a process by which bacteria can transfer genetic material from one bacterium to another through a bacteriophage (a virus that infects bacteria). The correct statement for bacterial transduction is option 'A': Transfer of some genes from one bacteria to another bacteria through a virus.
Explanation:
Bacterial transduction involves the following steps:
1. Infection by Bacteriophage:
- The process of transduction begins when a bacteriophage infects a bacterium.
- During infection, the bacteriophage injects its DNA or RNA into the bacterial cell.
2. Replication of Bacteriophage:
- Once inside the bacterial cell, the viral DNA or RNA takes control of the host cell's machinery.
- The viral genetic material directs the synthesis of new viral components.
3. Packaging of Bacterial DNA:
- In some cases, during the assembly of new viral particles, small fragments of bacterial DNA are mistakenly packaged into the viral capsid instead of viral DNA.
- These fragments of bacterial DNA can be from the bacterial chromosome or plasmids.
4. Release of Bacteriophage:
- Once the new viral particles are assembled, the bacterial cell is lysed (ruptured), and the newly formed bacteriophages are released into the environment.
5. Infection of New Bacterial Host:
- The released bacteriophages can then infect new bacterial cells.
- During infection, the viral genetic material is injected into the new host bacterium.
6. Incorporation of Bacterial DNA:
- When the viral DNA enters the new host bacterium, it can integrate into the bacterial genome or exist as a separate plasmid.
- The bacterial cell can then express and replicate the transferred genes, leading to the acquisition of new traits.
In summary, bacterial transduction is a mechanism by which bacteria can acquire new genetic material from other bacteria through the transfer of genes mediated by bacteriophages. This process allows for the exchange of genetic information between bacteria and contributes to the genetic diversity and evolution of bacterial populations.

In transduction, genetic material of one bacterial cell goes to other bacterial cell by agency of bacteriophages or phages (viruses, infecting bacteria). Transduction was first of all reported in Salmonella typhimurium by Zinder and Lederberg (1952). Transduction is used for gene mapping and analysis in bacteria and also for strain construction.
