Cloning Essay -- essays research papers fc

Cloning For many years, the cloning of adults, animals or humans has been mostly the object of science fiction, something unforeseen by man. However, â€Å"The world was shocked in February of 1997 when British scientist, named Ian Wilmot announced that his research team successfully cloned lamb named dolly from an adult sheep at the Roselyn Institute in Scotland†.(1) For what seemed like a dream for many years quickly turned into reality. The newest and possibly the most controversial phenomena in curing human disease, a phenomenon better known as cloning, was born. Through out the history of man, human disease has been considered a leading cause of death. Since antiquity, physicians explored assorted remedies in order to cure various maladies. Ancient physicians made enormous contributions to modern medicine. Even though, immaculate progress has been made in modern medicine, there are numerous cases of fatal diseases, for which modern medicine has no cure. Granted today’s technological advancements, general practitioners are still using several of the ancient techniques and ideas in order to make progress in today’s research and development. Scientists observe historical data and ideas in order to help generate new ones. A well known belief to man, the belief of reincarnation came from the ancient Egyptians who believed that there was life after death and preserved the body of their rulers through a process of mummification. This is a process of preservation that kept the original body and shape of the ruler for his/her return to earth. Although, this may seem a bit anomalous to the western man, contemporary technology brings this the idea of reincarnation or recreation to life, creating new ways to fight disease. Modern science takes the idea of human life and it’s regeneration and brings it to life through the process of cloning. In 1938 a German scientist Hans Spemann proposes a "fantastical experiment" to transfer one cell's nucleus into an egg without a nucleus, the basic method that would eventually be used in cloning. Fourteen years later in 1952 Briggs and King clone tadpoles. Another scientist John Gurdon clones frogs from differentiated cells in 1962. In 1969 Shapiero and Beckwith isolate the first gene. By 1973 Cohen and Boyer create first recombinant DNA organisms. 1978, the release of David Rorvik's book, In His Image: The Cloning of a... ...reproductivecloning.net/hosting/waite/#1: 5) CNN.COM February 28, 2002 Posted: 6:24 AM EST (1124 GMT) ACCES DATE APRIL 18 202 C:Documents and SettingsRafaelMy DocumentsCNN_com -Superman star hails cloning move - February 28, 2002.htm 6) http://www.bioexchange.com/news/news_page.cfm?id=11426 Outline Topic/Thesis: The newest and possibly the most controversial phenomena in curing human disease, a phenomenon better known as cloning, was born. 1) Origin of human cloning a) Reincarnation b) From 1938-dolly c) Feb. 1997 Ian Wilmont announces the birth Dolly 2) Pros/cons + Treating disease + Benefit economy + Feed the needy - Violates animal rights - Took 277 attempts to clone Dolly - Expensive 3) Three types of cloning a) Embryo cloning b) Adult DNA cloning c) Therapeutic cloning 4) Recent development a) January 2001-An endangered Asian ox called a gaur dies two days after birth of an ordinary disease after it was cloned and gestated in the womb of a cow.
