Who discovered the plasmid vectors ?

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
