When a recombinant DNA is inserted within the coding sequencing of an enzymes, `beta`-galactosidase

What would happen if a recombinant DNA is inserted within the coding sequence of an enzyme, beta -galactosidase ?

True and false : In recombinant DNA, DNA inserted within the coding sequence of an enzyme beta galactosidase.

In the process of insertional inactivation 1) a recombinant DNA is inserted within the coding sequence of enzyme β -galactosidase, resulting in inactivation of the enzyme 2) a recombinant DNA is inserted within the coding sequence of proteins involved in the replication of the plasmid 3) a recombinat DNA is inserted within the recongnition site for EcoRl 4) none of these

If recombinant DNA is inserted within the coding sequence of enzyme galactosidase, which of the following will occur in case of non -recombinants

If a person obtains transformants by inserting a recombinant DNA within the coding sequence of enzyme beta-galatosidase, he will separate out recombinants from non-recombinats by which of the following observations ?
