Even since a little lamb came forward saying that cloning of mammals is possible the world has been in a state of bewilderment.  This means that if cloning a sheep is possible, how far away are humans?  Is there a new generation of Dr. Frankensteins coming?  I hope to answer this question, the process of cloning, the positive and negative aspects, ethical aspects, and an authors view of cloning all the way back from the 1940's.  The basics however, are the first part.
The process of cloning is involved.  This process includes both embryo and adult DNA cloning.  Embryo cloning, which was been around the longest, is the less complicated of the two.  Embryo cloning is not really cloning for say.  It is more of a twinning process.  It has been used in mice since the late 1970's and other animals since the 1980's.  The process is really quite simple.  An egg and sperm are mixed together in a petri dish.  When conception occurs the zygote develops into a blastula.  After dividing into a couple stages, a chemical is added to remove the "zona pelocide" which promotes cell division.  The blastula is then divided into separate cells, recoated, and then allowed to further develop.  Adult DNA cloning however is a little more complicated.
Adult DNA cloning was thought to be impossible until Dolly was created.  It involves the use of nuclear transfer technology ("Human Cloning").  It was used quite successfully in the past, especially for embryo cloning, but never for primates (Baker).  It is also noteworthy that Robert J. Stillman and his colleges at the George Washington Medical Center were the first group to go public to say it is possible.  They took seventeen unusable embryos (each had two sperm for fertilization) and managed to split each successfully.  They also reported on the best ways to split them and how long they should be allowed to develop.  All of the zygotes had the potential to become a fetus had they not been previously defective ("Human Cloning").
The limits on cloning are very undecided now.  The limits on Dr. Wilmut were very significant; it took him 277 tries to produce one Dolly (Motavalli).  And it is not the scientific limits that everyone is worried about, its congressional limits.  Dolly's creator, Dr. Wilmut is in favor of a limit for human cloning because he feels his progress can be used elsewhere better ("Dolly").  Republican George Brown of California stated, "It is significant that Congress followed the lead of the scientific in discu...
