The method used to clone Dolly was scientists at the Roslin Institute in Scotland took a cell out of the mammary gland. They then used an electrical pulse to coax an adult cell into merging with a host egg whose nucleus had been removed (Hoon). This method being very unsuccessful brought on a new one where scientists used mice, injecting just the adult nucleus into a nucleus free host instead of using an electrical pulse. They also had let it set for two hours before stimulating it to start dividing. The success rate was 2-3 in 100. Now knowing that we could clone sheep and mice, scientists were up to the possibility and challenge of cloning humans. As soon as it became public knowledge that cloning was really happening and becoming more successful, President... [continues]
