Cloning And Embryo Research
Words: 868 / Pages: 4 .... 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 for nearly a decade to create genetically altered mice (Travis Par. 8). Kaye Tucker of World Socialist Web Site writes, “These basic cells are present in the earliest stages of developing embryos and are able to develop into virtually any type of cell and tissue in the body” (Par. 3). .....
