It turned out the cell that we were trying to transplant into had a nuclease, an enzyme that chews up DNA on its surface, and was happy to eat the synthetic DNA that we gave it and never got transplantations.
S-a dovedit că celulele în care vroiam să facem transplantul aveau o enzimă - nuclează - care distruge suprafaţa ADN-ului. şi mânca cu mare plăcere ADN-ul sintetic pe care îl introduceam noi. şi nu obţineam niciodată transplantul.
