Which of the following human proteins, obtained from transgenic animals, is specifically used for the treatment of emphysema?

Step-by-step solution

Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product. The human protein - 1 -antitrypsin is produced by transgenic animals and is used specifically to treat emphysema. Human -lactalbumin is the protein produced in the milk of the transgenic cow Rosie. Insulin for human use is primarily produced using recombinant bacteria, not transgenic animals. Cry protein is an insecticidal protein produced by the bacter
