Which of the following is a correct sequence of steps in a PCR (Polymerase Chain Reaction)?
Plasmid $\mathrm{pBR}322$ has PstI restriction enzyme site within gene ${\mathrm{amp}}^{R}$ that confers ampicillin resistance. If this enzyme is used for inserting a gene for $\beta$-galactoside production and the recombinant plasmid is inserted in an E. coli strain
