Cloning of a sheep

• From a sheep extracted ovum;
• Ovule takes off the nucleus with DNA;

• Since this cell is extracted the nucleus, whose DNA contains the entire genetic heritage;
• The core of mammary cell is entered into the ovule;
• The egg is implanted in the uterus of a host sheep and it develops the embryo;
