The first transgenic buffalo, Rosie produced milk which was human alpha-lactalbumin enriched.
Restriction enzymes are used in isolation of DNA from other macromolecules.
Downstream processing is one of the steps of rDNA technology.
Disarmed pathogen vectors are also used in the transfer of rDNA into the host.
Options:
Answer:
Solution:
In 1997, the first transgenic cow, Rosie, produced human protein enriched milk. The milk contained the human alphalactalbumin and was nutritionally a more balanced product for human babies than natural cow milk. Isolation of DNA from other macromolecule is achieved by treating the bacterial cells/plant or animal tissue with enzymes such as lysozyme (bacteria), cellulase (plant cells), chitinase (fungus).
