Transduction is another parasexual mechanism of gene transfer employed by bacteria. This phenomenon is mediated by a bacteriophage. Essentially, it requires the packaging of bacterial DNA in a phage head, while the phage may be growing inside the cell, and then transfer of this DNA to another bacterial cell in the next round of infection. Conventionally, the former cell is referred as a donor and the latter as the recipient cell. Once inside the recipient cell, the transduced DNA may undergo recombination to yield a transductant. Thus, unlike transformation and conjugation which follow dedicated pathways, transduction appears to be an accidental outcome of phage infection.
