A number of foreign proteins have been expressed in bacterial and mammalian cells. Describe the essential features of a recombinant plasmid that are required for expression of a foreign gene. How can you modify the foreign protein to facilitate its purification? What is the advantage of expressing a protein in mammalian cells versus bacteria?

Give a specific example of how the introduction of a gene into a bacterium can change the phenotype of the bacterium. Also explain the specific role of the protein expressed by the gene in changing the bacterium's phenotype. You have isolated one of the genes for producing one of the blood-clotting proteins needed by some hemophiliacs. Briefly describe how you could create bacteria that would produce this protein.
