What is unique about transduction compared to normal bacteriophage infection?

Room for genetic recombination

Explanation:

Bacteriophage is a virus, and like every virus, it needs a living host cell to reproduce. Hence, bacteriophage is a virus that infects bacteria cells. It attaches itself to its bacterium host cell and infects it. After infection, the bacteriophage hijacks the bacterium's ability to replicate and transcribe its genes and use it to produce several viral components or virons.

Transduction is one of the methods of gene recombination in bacteria cells. During the infecting cycle of a bacteriophage, a portion of the host's DNA (bacterium) occasionally becomes incorporated into the genome of the bacteriophage, and then conveyed to another host when it initaites another cycle of infection.

Since bacteria cells undergo asexual reproduction (binary fission), all resulting cells are identical to their parent cells, hence, there is no room for genetic variation among the species. Transduction, among other methods of gene transfer, is a way to ensure genetic diversity in bacteria species.
