DREAMS SOMETIMES COME TRUE ! Bioteghnology has the possibility to be revived a scare and an extinct animal (Film Jurasic Park) The birth of the clone animals is great influencing the frontier of research of animal reproductive biotechnology Why ? Somatic cell (deferentiated) was reprogramed back to embryonal stage and resulted in normal offsprings.
