15.2 Ligation of Antibiotic Resistant Plasmids
In this week's laboratory, you will complete your study
of genetic engineering (biotechnology) by constructing a
recombinant DNA plasmid which contains genes for both
ampicillin resistance and kanamycin resistance.
In this laboratory, you will use your digested antibiotic
plasmids (Figure 15.1) from last week's laboratory to recon-
struct a recombinant plasmid which possesses both the
ampicillin resistance and kanamycin resistance genes. You
will begin by heating your restriction digests of pAMP and

PKAN to destroy BamHI and HindIII activity. A sample from
each reaction will be mixed with DNA ligase plus ATP and
incubated at room temperature. Complementary BamHI and

fragments. Ligase catalyzes the formation of phosphodiester
bonds that covalently link the DNA fragments to form stable
recombinant DNA molecules.
