1.	Question : 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 ?
Answer» Solution :Alternative selectable marker separates Alternative TRANSFORMED and non - transformed molecules on the basis of their COLOUR like recombinant DNA is inserted with the coding sequence of an ENZYME, `beta` galactosidase. This results into inactivation of the gene for synthesis of enzyme, which is referred to as INSERTIONAL inactivation.
