A Miracle for Mankind Cloning is not an easy task, but because of such a growth in research it is worth the difficulties to carry out such an experiment. Cloning is based on nuclear transfer, which involve the use of two cells, the same technique scientists have used for some years to copy animals from embryonic cells. The technique where by a female's egg is removed, put into a Petri dish, and then fertilized by sperm. More than one sperm fertilizes the egg so it causes the egg to split. The egg does this naturally, exactly how twins are produced. Then the zona coating is removed with an enzyme, and the two eggs are separated. Next, there is an artificial zona coating added to allow the development to proceed around each of the eggs. The cells, at that point, continue to divide and form genetically identical embryos. This procedure will make the future progress for scientific technology more useful. Many Americans believe that cloning interferes with nature, whether it be with animals or humans. Once a mammal is cloned, it gives a whole new perspective to the world, and numerous people grow angry at cloning, scientists, people, research, clone, animals, technology, cells, medical, organs, human, diseases, humans, because, organ, world, out, now, genetic, future, way, about, using, treatments, technique, person, lives, life, heart, genetically, genes, couples, work, without, states, researching, problems, new, kolata, infertile, disease, come, children, cancer, been, through, surgery, scientific, save, put
