Now, when these harmless bacteriophages infect other cells, other bacterial cells, they inject the cells, they inject into the cells the DNA fragment from the other cell which can then be integrated with that cell's DNA. And this increases the genetic information of that bacterial cell. So basically, in a way, transduction takes place accidentally. So this is shown in the following diagram. So we have our bacterial cell that is hijacked by our bacteriophage. Now, instead of the bacteriophage taking up the viral DNA or RNA molecule, it takes up this fragment of DNA that came from our actual DNA of that bacterial cell.
