Answer
To cut the plasmid, a restriction enzyme is required. This enzyme recognizes specific sequences in the DNA and creates cuts at those sites, enabling the insertion of the foreign gene.

Answer
To insert the foreign gene into the plasmid, DNA ligase is necessary. This enzyme joins the cut ends of the DNA, facilitating the stable incorporation of the foreign gene into the plasmid.
