Chickens as Drug Factories

Scientists in Scotland have successfully produced five generations of chickens that lay eggs containing certain protein-based drugs. The scientists changed the DNA of the chickens so that two drugs, one used to treat skin cancer and the other used to treat multiple sclerosis, were present in the egg whites. Cows, sheep, and goats have already been altered to produce protein-based drugs in their milk. Chickens are considered good "drug factories" because they are inexpensive to care for, they grow fast, and their chicks inherit the special drug-producing ability.

Explain why scientists altered the DNA of the chickens instead of altering a protein already present in the chickens. In your answer, be sure to:


Identify the technique used to alter the DNA


Correct Answer: 

– genetic engineering – genetic manipulation – gene splicing – forming recombinant DNA
