Correct answer: A. Viruses
- A. Viruses
- B. Ingestion
- C. Binary fission
- D. Physical contact
Explanation
Transduction is a process of genetic recombination in bacteria where DNA is transferred from one bacterium to another through a third-party, the virus. This differs from other methods of genetic transfer like conjugation, which requires direct contact between cells, and transformation, where bacteria take up DNA from their environment. The options 'ingestion' and 'binary fission' do not involve the transfer of genetic material between bacteria. Ingestion is not related to bacterial recombination, and binary fission is a method of reproduction rather than genetic recombination.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
