In a PI transduction experiment, the PI lysate contains phages that carry pieces of the host chromosomal DNA, but the lysate also con-tains broken pieces of chromosomal DNA (see Figure 7.10). If a I'I lysate is used to transfer chromosomal DNA to another bacterium, how could you show experimentally that the recombinant bacterium has been transduced (i.e., taken up a PI phage with a piece of chromosomal DNA inside) versus transformed (i.e., taken up a piece of chromosomal DNA that is not within a PI phage coat)?
