Answer:
Advances in DNA technology has changed the working model in medical field and improved its services in several ways.
Advances in DNA technology are assisting the work of those in the medical fields in several following ways:
1) Recombinant DNA technology, gene therapy, and genetic modifications used for bioremediation.
2) Gene therapy is used to treat many genetic disease.
3) Several plant systems are used to form different antibodies and their derivatives, for example transgenic tobacco plants used for the production of chimeric secretory IgA/G.
4) Development of vaccines and recombinant hormones are used to treat several diseases, for example human follicle-stimulating hormone (FSH) can be prepare through recombinant DNA technology.
