In your research you are given two tubes of DNA: Tube 1 contains a purified PCR amplified human beta-globin locus that is about 2kb in size. This PCR product has intact Not I restriction sites flanking the gene. Tube 2 contains a 5.2 kb circular plasmid vector, pcDNA3.1 (-), containing a multi cloning site with recognition sites for Nhe I, Pme I, Not I, Eco RI, Hind III, and Pme I. This vector has the Neomycin and Ampicillin resistance genes. You want to clone the beta-globin gene into the pcDNA3.1 (-) vector. Describe the following: a) How you will ligate the beta-globin gene insert into the pcDNA3.1 (-) vector to create a recombinant molecule? (6 marks) b) How you will introduce this ligation mix containing the recombinant molecule into a host E. coli strain? (4 marks) c) How you will select for the transformants containing the recombinant DNA in the E. coli? (2 marks)

Part III: Discussion 1. What was the main goal for this lab? 2. What is bacterial transformation? 3. How do genetic engineers use restriction enzymes? 4. How do genetic engineers use ligase enzymes? 5. Where can you find plasmid DNA? 6. In order for this experiment to be successful the E. coli cells must be competent. What does that mean? 7. What did you do to make the bacterial cells competent?
