Immune cells have been genetically modified to treat cancer. stem cells, as well as other cells in tissues and organs in the human body, have been genetically engineered. for example, transgenes could be developed and delivered into pancreatic cells, to express insulin. if these transgenes were inserted into the genome of pancreas, those cells could become fully functional insulin producing cells as a cure for diabetes. this type of an approach to genetic modification is known as?

Gene therapy

Explanation:

Gene therapy is designed to introduce and infuse genetic material into cells to compensate for abnormal genes or make new proteins that are beneficial to the host. Gene therapy introduces normal copy of a gene to replace and restore damage genes that resulted from mutations, this process in turn bring back the original function of the particular protein and restores it's functioning.

it marks things for degradation via the proteasome. it alters there celluar location.
