Question

Transfer of genetic information from one bacterium to another in the transduction process is through

• A. bacteriophages released from the donor bacterial strain
• B. another bacterium having special organ for conjugation
• C. physical contact between donor and recipient strains
• D. conjugation between opposite strain bacterium.

Answer 1

Answer: (A)

Transduction is the phenomenon of transfer of genetic material from one bacterial cell to another through the agency of virus. The viruses carry a segment of DNA from one host and infect another host which is different from the first one, the latter may inherit some of the properties of the former host due to transfer of DNA segment through infecting phage.
