...Just as women have long been able to have children without a male sexual partner, through artificial insemination, men could potentially become dads alone: replace the DNA from a donor egg with one's own and then recruit a surrogate mother to carry the child. Some gay-rights advocates even argue that should sexual preference prove to have a biological basis, and should genetic screening lead to terminations of gay embryos, homosexuals would have an obligation to produce gay children through cloning...
...when the heart has stopped? They have to do direct massage of the heart. You could say the doctor is playing God. But we save a life. With human cloning, we're not so much saving a life as creating a new being by manipulation of the raw materials, DNA, the blueprint for life. You're simply using it in a more creative manner...
...field where emotions run so strong and hope runs so deep is fertile ground for profiteers and charlatans. In her effort to clone her daughter Olga, Tanya Tomusyak contacted an Australian firm, Southern Cross Genetics, which was founded three years ago by entrepreneur Graeme Sloan to preserve DNA for future cloning. In an e-mail, Sloan told the parents that Olga's teeth would provide more than enough DNA?even though that possibility is remote. "All DNA samples are placed in computer-controlled liquid-nitrogen tanks for long-term storage," he wrote. "The cost of doing a DNA fingerprint...
...debate over the ethical, emotional and practical implications of human cloning, identical twins?distinct beings who share the same DNA?present the closest analogy. Identical twins are in fact more similar to each other than a clone would be to his or her original, since twins gestate simultaneously in the same womb and are raised in the same environment at the same time, usually by the same parents...
...Other connections between Diana and me may be more related to our matching DNA and thus more applicable to clones. My twin and I filter information in much the same way, and we think, perceive and interpret things similarly. When we're together, we often respond simultaneously with the same word or sentence. We have put on the same T shirt on the same day in different cities. We have friends who are twins, both doctors, who have similar experiences. They took a pharmacy class together in medical school but sat across the classroom from each other and took separate...
