mi ez egyáltalánb

1. You wont change all the cells in your stomach lining

2. You need rigorous testing in vitro to see transfection efficiency and expression of lactase

3. The cells in your stomach lining cycle through so quickly anyways it doesnt matter that you transfected them

4. You'll definitely get off target transfections in any cell the virus comes in contact with, which still doesnt matter if your goal is to digest lactose, and is actually potentially dangerous

5. The virus is unsafe if it can hijack your cell's machinery to reproduce viral particles, which is a big concern for biosafety because you could potentially release this virus into nature

6. Gene recombination is still a shot in the dark experiment. There's no guarantee any sort of gene editing happened or even the kind of edits that he wanted. Its very possible the edits happened somewhere else on the genome
