What is virus transduction?

Phage viruses acquire bits of bacterial DNA as they infect one cell after another. This process, which leads to genetic recombination, is called transduction.

During the lysogenic cycle, a phage integrates into the host cell at a specific site. At a later time, when the phage ruptures out of the host DNA, it sometimes carries a piece of adjacent host DNA with it and inserts this host DNA into the next host it infects.
