They took some of this same pickled thylacine DNA and they spliced it into a mouse genome, but they put a tag on it so that anything that this thylacine DNA produced would appear blue-green in the mouse baby.
Agarraram num pedaço do ADN  deste tilacino em conserva e ligaram-no a um genoma de rato, mas puseram-lhe um marcador, de modo que tudo o que esse ADN  de tilacino produzisse aparecesse verde-azul na cria do rato.
