     Cloning, is it the thing of the future?  Or is it a start of a new
generation?  To some, cloning could give back a life.  A life of fun, happiness,
and freedom. For others it could mean destruction, evil, or power. Throughout
this paper, you the reader, should get a better concept of cloning, it's ethics,
the pro's and con's, and the concerns it has brought up.  You will hear the good
of what cloning can do and the bad that comes with the good. Most of the
information you will read about in this paper is what might become of the future.
Even though the cloning of humans can not be accomplished.  When it is the
possibilities are endless.

     What is cloning?  How did it get started? Well, it is like this.  A
clone is a genetic copy or a replica of an living organism.  But, when you gear
cloning doesn't a Si-Fi movie come to mind. Like when they take a nucleus, place
it in a egg, put the egg in a incubator, and when it hatches it's an exact
replica of the original being (Lawren).  Though this has been done with frogs it
has not yet been accomplished with mammals (Lawren).  Another way to make a
clone, as they do in the cattle buisness, is to split the cells of a early
multi-celled embryo which will form two new embryos (Lawren).

     For it to get started into practice it took more than fifty years of
questioning and testing.  The first successful cloning experiment involved a
leopard frog.  It  took place in, 1952 with group of  scientist from the
Institute for Cancer Research in Philadelphia (Lawren). To clone the frog they
used an embryonic frog cell nucleus(Margery). 1962, John Gurdon of Cambridge
University cloned a toad that survive threw adulthood and was able to reproduce.
He was also the first to take a nucleus from a fully contrast tadpole intestinal
cell and cloned toads(Robertson).   As you can see we are getting close to the
cloning of humans.  1981, Steen Willadsen was the first to clone a artificial
chimera. He did this by mixing a sheep and a goat getting the result of a "geep"
(Lawren).  It had the body shape and the head of a goat, and a dappled coat
which had large patches of sheep's wool.  1984, Willadsen cloned the first
verifiable mammal, using embryonic nuclei transplant into an unfertilized sheep
egg.  Also in, 1986, when he worked for Texas bioengineering company (Lawren).
By using the embryonic nuclei, he produces the first cloned calves from cattle.
The cloned cattle that were produced we...
