plasmid vectors
B

D
F-factors.
Answer
phage vectors
Explanation
Solution
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.
