who is God?and he belongs to which religion?
whom we should believe?The God or the prechers?
Or we can become God by cloning?

The routine genetic modification of animals to create healthier food products may be the most dramatic legacy of the remarkable cloning experiment in Scotland that produced Dolly, the world's first mammal cloned from an adult cell.

But that is at best decades away, many geneticists say. In the nearer term, Dolly's creation is likely to bring less visible but profound changes in medicine, where advances increasingly depend on understanding and manipulating the genetic process. Among them:

Animals that do the best job of producing organs for transplant or proteins used as drugs for humans could be cloned, to preserve those traits.

Cloning could help produce genetic "models" of human diseases, so that researchers could understand them and develop cures.

Cloning could bring new insights into the process of aging.

"The important thing is not so much to produce a clone, but to get from an adult cell to an animal," said Ron James, chief executive of PPL Therapeutics in Edinburgh, Scotland, whose company collaborated with neighboring Roslin Institute to create Dolly and holds commercial rights to the cloning technology. "There is a huge amount of scientific benefit from this."

PPL's immediate plan for cloning technology is to create "transgenic," or genetically modified, sheep to produce, in their milk, human proteins that are used as drugs. These therapeutic proteins, such as blood-clotting factors and growth hormones, now are derived from donor human plasma or reproduced in bacterial and mammalian cells.

Under PPL's process, the human genes for the proteins are inserted into fertilized eggs of sheep to raise what are in effect living protein drug factories. Cloning would be employed to replicate those ewes that produce the greatest quantity of the protein.

PPL also is creating transgenic sheep to produce proteins for treating cystic fibrosis and blood clotting disorders. The company has a laboratory facility in Blacksburg, Va., where it raises transgenic cows to produce in their milk nutritional supplements for human infant formula.

Another possible use for cloning is the development of pigs that have been modified with human genes so their organs can be transplanted into humans. The genes are injected into pig embryos to create the transgenic animal. The value of cloning in this case also would be in selecting the best adults to clone and breed to expand the stock.
