(e) Laboratory-produced phages can be used as delivery tools in DNA vaccines, which will allow the expression of immunogenic proteins to the organism that received them (f) Pseudoviral particles (VLPs) are produced in cells that receive expression vectors…arrow_forwardAn elderly woman took a prescription medicine to help her to sleep; however, she felt restless all night and did not sleep at all.
