Another possibility is that the aging process is linked
to the number of normal mitochondria the individual possess
per cell..... the nucleus of the adult cell was transplanted
into the denucleated egg of another sheep - the mitochondria
of which should all be fully functioning.
Also telomerases might be active in the early embryo which
are switched of in the adult (?) lengthening the telomeres
and thus extending the division rate of the cell (?)
But these (previous to this reply)are interesting speculations
and they go to show that
the cloning has already stimulated scientific discussion as well
as, alas, the more excitable members of the general
population.
