Answer:
A reporter gene can be used to monitor the transformation of host cells by foreign DNA. They act as a selectable marker to determine whether the host cell has taken up the foreign DNA or the foreign gene gets expressed in the cell. ... Then, this combined DNA construct is inserted in the cell.

Answer:
In non-transformed cells, this gene is expressed and the catalyzed product is formed. This results in the blue coloration of the colony. Thus, reporter enzymes can be used to monitor the transformation of host cells by foreign DNA besides being a selectable marker
