What type of genetic recombination in bacteria involves dna transfer by viruses?

Transduction is a technique that allows geneticists to introduce genes into cells by engineering viruses to include their gene of interest. This work was first used in bacteria because there is such a wide variety of well-characterized bacteriophages (viruses that affect only bacteria). Today adenoviruses, retroviruses and lentiviruses are all used commonly in biomedical research to transduce mammalian cells.
