Question 17

You are a scientist who wants to produce large amounts of the protein insulin that is used to facilitate the entry of glucose into cells. You know that insulin genes may be introduced into bacteria by way of a plasmid vector. These bacteria may then be used as 'micro-manufacturers' of insulin. Your laboratory technicians explore various methods of producing the desired bacteria, but you are not sure how many and which of the bacterial cells have been transfected (have the plasmid with the insulin gene). Propose a way to determine which bacterial cells have been transfected with the engineered plasmid and are able to produce insulin.

Accepted Answer

The answer may vary. One way of determining if the process has been successful is to add (ligate) the gene that confers antibiotic resistance to the insulin gene you are inserting into the plasmid. Now every plasmid that contains the insulin gene (your target gene) will not be killed by antibiotics. After you introduce the engineered plasmids (the one with the target gene -insulin- and the antibiotic resistant marker) into your bacterial cells, you incubate them in a nutrient broth that also contains antibiotic (usually ampicillin). Any cells that were not transfected (that do not have your target gene in them) are killed by the antibiotic. The ones that do have the gene also have the antibiotic resistant gene, and therefore survive the selection process. You now know which bacteria have the insulin genes.
