Applying Genetic Engineering medical applications pharmaceuticals - uses bacterial cells to mass produce certain proteins cheaply o recombinant genes introduced into bacterial cells o used to produce insulin, interferon, growth hormones, erythropoietin o atrial peptides - small proteins to treat high blood pressure o tissue plasminogen activator - human protein that causes blood clots to dissolve o hard/expensive to purify proteins produced by bacterial cells genetic therapy - started in 1990 in attempt to fix genetic defects o replaces defective gene w/ working copy piggyback vaccine - aka subunit vaccines, used against viruses o uses DNA of benign vaccinia virus to make vaccines, stimulate immune system o DNA vaccine - depends on killer T cells instead of antibodies to stop viruses agricultural applications limited number of possible vectors for plants Ti (tumor-inducing) plasmids - infects broadleaf plants o doesn’t infect cereal plants (corn, rice, wheat) “Flavr Savr” - has genes that inhibit ethylene production, delaying over-ripening
