The possibilities created by cloning are virtually endless.
If perfect organisms can be cloned, life on earth can be perfected.
Listed here are just some of the possibilities:
||Good genes can be cloned to replace bad genes in a host cell.
This therapeutic process of DNA cloning can be used to save many
||Genes from different organisms that improve taste and nutritional
value or provide resistance to particular types of disease can be
used to genetically engineer food crops.
||If the low success rates can be improved (Dolly was only one success
out of 276 tries), animals with special qualities can be reliably
reproduced. For example, drug-producing animals or animals that
have been genetically altered to serve as models for studying human
disease could be mass-produced.
||Endangered animals or animals that are difficult to breed can
be repopulated through the process of reproductive cloning. An endangered
wild ox called a gaur and an endangered wild sheep called a mouflon
have already been cloned (in 2001) in Italy.
||Therapeutic cloning technology may some day be used in humans
to produce whole organs from single cells or to produce healthy
cells that can replace damaged cells in degenerative diseases such
as Alzheimer's or Parkinson's.
||If humans can be cloned, whole armies of the "perfect"
people can be created. Although this idea sounds scary, it might
well be possible some day.
