Final answer:
Transduction is a form of bacterial recombination that involves a viral intermediate. Bacteriophages transfer short pieces of chromosomal DNA from one bacterium to another, facilitating the spread of genetic information between bacteria.
Step-by-step explanation:
The form of bacterial recombination that involves a viral intermediate is called transduction. In transduction, bacteriophages, which are viruses that infect bacteria, transfer short pieces of chromosomal DNA from one bacterium to another. This process results in the transfer of genetic information between bacteria through viral infection.
