Answer :
"The desired gene is inserted into the genomes of the pork" sentences explains how pork is genetically engineered.
Explanation:
The sequencing of the pig genome represents a significant tool for further development of this essential animal species, and our discovery of many putative disease-causing variants increases the pig's potential as a biomedical model.
If all the genes in the pork's genome are altered the cells would not make the appropriate proteins and they could die. Plasmids are trash DNA and no function will be done. In addition, plasmids are found in bacteria, not in the eukaryotic cells.
