The mechanism by which genes are transferred into bacteria with the use of bacteriophages (viruses) is called transposons. replicaplating. transformation. transduction. conjugation.

The correct answer is transduction. Here, foreign DNA is introduced into a cell using a virus or viral vector. Most typically, DNA will be transferred from one bacterium to another using this technique. The advantage of the technique is that physical contact between the donor and receiving cell is not required, and the mechanism is not susceptible to DNase. Transduction has become a routine tool used by molecular biologists to introduce a new gene into a host's genome.
