Can you think and answer how a reporter enzyme can be used to monitor transformation of host cells by foreign DNA in addition to a selectable marker?

Explanation

A reporter gene can be used to differentiate transformed cells by tracking down the activity of its co-responding genes (receptor gene). It can be used to monitor the transformation of host cells by foreign DNAgt they act as a selectagle marker to determine whether the host cell has taken up the foreign DNA or the foreign gene gets expressed in the cell. The researchers place the reporter gene an the foreign gene in the same DNA construct. Then, this combined DNA construct is inserted int he cell. Here, the reporter gene is used as a selectable marker to find out the successful uptake of genes of interest (foreign genes). An example of reproter genes includes lac Z gene,which encodes a green gluorescent protein in a jelly fish. theother, which appear blue in colour, indicate that cells do not carry foreign DNA.
