Final answer:
The insertion of a p element into DNA can result in integration into chromosomal DNA or the p element remaining in the donor cell.
Step-by-step explanation:
When a mobile genetic element called a p element is inserted into the DNA of an organism, it can have different outcomes.
One possible outcome is the integration of the p element into the recipient cell's chromosomal DNA, resulting in the recipient cell becoming an Hfr (High-frequency recombination) cell.
Another outcome is that the p element remains in the donor cell, making the recipient cell a new donor cell with the p element.
