I wonder what happens if these animals escape? Makes me think about The Secret of NIMH.
Pharming: "...several companies worldwide perfecting the art of "pharming" -- genetically modifying animals to churn out drugs for disorders like hemophilia and cancer."
How they do it: "It involves genetic modification of an animal embryo's genetic makeup, or genome. Just after fertilization, "pharmers" insert into the embryo a human gene that codes for a particular protein -- usually one that's produced naturally in humans, but that's lacking in people who have certain diseases. They attach that DNA code with a gene that codes for a sugar found in mammalian milk, insuring that the therapeutic protein will be expressed only in the animals' milk or eggs."
