Cloning and Embryo Research

The idea of cloning a life form seemed like something read from a science fiction novel just ten years ago. Now, the theories, ideas and facts of cloning embryos have made cloning one of the most talked about social issues of our time. The researchers of this scientific breakthrough have made a lot of progress in recent years. Many have heard of Dolly, the cloned sheep, and that’s just the tip of the ice burg. This is undoubtedly the biggest and most recent breakthrough science has seen in some time.

Cloning research started in Scotland. According to an article in Science News Online, “Scottish investigators grew embryo cells of Welsh mountain sheep in the laboratory. During a relatively stable stage of the cell cycle, they transferred 244 of the nuclei to the stripped-down eggs of Scottish blackface ewes” (Adler Par. 8). These nuclei had a full set of chromosomes, so fertilizing the eggs was not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the area of embryo stem cells. Scientists have used such mouse stem cells
