A clone is really just a time-delayed identical twin of another animal or person. Cloning
is accomplished by getting two cells to fuse to become one. The egg gains a full set of
genes from the adult and thinks it has been fertilized. Then it begins to divide and
become identical twin or clone of the adult.
There are many different good things that could come from this new science. One way it
would be helpful is reversing heart attacks. Some scientists believe that they would be
able to treat heart attack victims by cloning their healthy heart cells and injecting them
into the areas of the heart that have been damaged.
Another helpful way cloning would be. Is to create organs or tissues to replace damaged
ones. Some scientists believe that it would be possible to create these tissues or
organs. Human cloning can also help parents that can not have a child have one.
One more way cloning would be helpful in animals is that we could create the perfect
animal that would produce what we wanted. It would have no flaws and would live long
enough. It would also be immune from diseases.
