Already biologists studying the cell’s(59)workings and the various methods of cloning have made discoveries that may ultimately lead to breakthroughs(60)the fight against cancer, control of the aging process, and the conquest of more than 100 presently incurable human genetic diseases. To(61)cloning-related research would mean closing the door(62)and important area of knowledge. To continue to probe the secrets of the cell, however, is perhaps to(63)the secret of human cloning. And, given the nature of man, if it can be done it will be done. What then is the(64)?
