One should know that grafting a DNA sequence in another organism's genetic material would cause the host organism to have a slight change, be it functionally or characteristically.
And it was a really good way in order to produce something or any kind of organism which was hard to come by or was especially rare.
But even this method was not viable to work in the SPECIAL CELLS at all.
It was because every cell that they had examined seemed much like that of a human being and in fact, they were indeed cells of humans, but each of them had their genetic material different.
Or it would be better to say that it was incomplete.
If one of the cells would have some part of the genetic material then the other would not and vice versa.
But there was also quite a big difference in the genetic material of these cells and that of a normal human being.
