This site tells about cloning of how it works, how it is done, what are the benefits, and what the problems are (to the public).</div> <bR> <div> This web site is made by a High School student that currently attends Edmonds-Woodway High School in Washington.</div> <div> This web site is made for a science project in Biology. </div> <bR> <div> I hope you enjoy this web site and you find it to be a good source of information.</div> <bR> <bR> <div> A Brief History of Cloning and Dolly</div> <bR> <div>  The first transfer of a nucleus into a cell occurred in the year 1952, by two men named Robert Briggs and Thomas King in Philadelphia. They used a Leopard frog. THey first of all transferred the nuclei into a Leopard frog egg. The drawback is, is that the egg sells did not develop. One of the first successful nucleus transfers of embryo cells however was by a man named Dr. John Gurdon in the 1970's, also using frogs. It all went pretty good, but the tadpoles that were developed, never got any older.\</div> <bR> <div>  Cloning was attempted by many other scientists, but failed and believed that it was impossible, they gave up, leaving only a few scientists behind, for further research. Finally, in 1984, Dr. Steene Willadsen said that he has successfully cloned a sheep. There were other successes, and cloned things such as cows and mice. Two years later, Dr. Wilmut and Dr. Campbell, who worked in the Roslin Institute in Edinburgh, Scotland, produced the first cloned sheep, the two sheep were named Megan and Morag. They used a different technique, and this will be explained on The Results of Cloning page.</div> <bR> <div>  Many believed that Dolly was the first ever cloned sheep, but they are wrong, I once believed that Dolly was the first cloned sheep also, but found out during the process of constructing this web site. The reason why the clone Dolly is so significant is because it was the first cloning of a mammal from an adult cell. This clone was produced by Dr. Wilmut and Dr. Campbell also. So basically they took a mammary cell from a sheep, put it into an egg, let it grow into an embryo, and put into an ewe, which acts as a surrogate mother. Dolly was born in a shed on the day of July 5th, 1996, weighing 141/2 ounds and considered healthy. Also to help were a group of uncredited graduate students, they did most of the labor, but did not come up with the techniques.</div> <bR> <DIV ALIGN="LEFT"></DIV> <div>  </div> <bR> <bR> </td> </tr></table></body>
