In conjugation, DNA passes through an extension on the surface of one bacterium and travels to another bacterium (Figure below). Bacteria essential exchange DNA via conjugation. In transformation, bacteria pick up pieces of DNA from their environment. In transduction, viruses that infect bacteria carry DNA from one bacterium to another.
