Which headline would be an example of genetic engineering?
a.) mrs. o'hara gives birth to fourth redhead
b.)farmer brown's pigs: best quality ham for the money
c.) gene added to liver improves clotting time
d.) bacteria make human insulin

The correct answer is option D, Bacteria Make Human Insulin

A bacterium is made to produce insulin through the technology “Recombinant DNA”.  Recombinant DNA technology is the process through which a human gene is inserted into the genetic material of bacterium by removing a loop from DNA of bacteria known as plasmid. The plasmid is then again returned to the DNA and recombinant bacteria is then placed in a large fermentation tank to synthesize insulin.
