1. Although the cause of the abnormalities is not known, many scientists suspect that the problem lies at the heart of the cloning process. 2. And Hawthorne admits there will be animals born with abnormalities as they perfect the cloning process. 3. And unlike other mammals, dogs excrete immature eggs from their ovaries, making it hard to obtain the mature eggs needed to start the cloning process. 4. Conceivably, for instance, the university could bar people created overseas by its cloning process from entering the United States. 5. Errors seem to spring from the stem cells, rather than the cloning process itself. 6. In the cloning process, instead of fertilizing donor eggs with sperm, ACT scientists chemically tricked eggs into dividing after replacing their DNA with cells from another person. 7. In the cloning process, the genes of a cell are implanted into a human egg from which all the genetic material has been removed. 8. Over and over again, he would start the cloning process and then the cells, like those in the Advanced Cell Technology study, would simply die. 9. Rather, leading cloning experts and developmental biologists said in recent interviews that the cloning process seems to create random errors in the expression of individual genes. 10. She decided to go back and take apart the cloning process, trying to figure out what was going wrong. |
