WebJan 3, 2024 · In transduction, bacteriophages, the viruses that infect bacteria, sometimes also move short pieces of chromosomal DNA from one bacterium to another. Transduction results in a recombinant organism. Archaea are not affected by bacteriophages, but instead have their own viruses that translocate genetic material from one individual to another. WebJul 26, 2024 · Bacteria change genetically by exchanging genetic material, absorbing genetic material and by losing genetic material.
