2. Discussion(刘论法 Back Puzzle 2 Will it be possible to clone the dead? (Para. 6) Discussion: Perhaps, if the body is fresh, says one expert. The cloning method used by Wilmut's lab requires combining an egg cell with the nucleus of a cell containing the DNA of the person to be cloned And that means that the nucleus must be intact. cells die and the cell nucleus begins to break apart after death. But, yes, in theory at least it might be possible.(Para. 7) >>>more

2. Discussion(刘论法 Back Puzzle 3: Would a cloned human be identical to the original?(Para. 8) Discussion: Most of the physical differences between originals and copies are so minor that detection of them would require a sophisticated laboratory. The only possible exception is bearing children. Wilmut and his coworkers are not sure that Dolly will be able to have lambs.They will try to find out once she's old enough to breed. (Para. 10) >more
