Assume that you are trying to insert a gene into a plasmid. Someone gives you a preparation of genomic DNA that has been cut with restriction enzyme X. The gene you wish to insert has sites on both ends for cutting by restriction enzyme Y. You have a plasmid with a single site for Y, but not for X. Your strategy should be to

What is the most logical sequence of steps for splicing foreign DNA into a plasmid and inserting the plasmid into a bacterium?

I. Transform bacteria with recombinant DNA molecule.

II. Cut the plasmid DNA using restriction enzymes.

III. Extract plasmid DNA from bacterial cells.

IV. Hydrogen-bond the plasmid DNA to non plasmid DNA fragments.
