History of Cloning

Although the word itself has only been around for only four decades, the idea of creating an organism identical to another has been around for centuries. Even nature has utilized this process. The actual process of artificially cloning has been around since before 1900s, even though it is heard of more often in the modern world. Cloning began in 1894 with the first clone of an organism. Hans Dreisch was able to clone a sea urchin, and his research led to Hans Spemann’s multiple attempts and successes of cloning throughout his science years. As technology advanced, Robert Briggs and Thomas King used Spemann’s results to create the process of nuclear transfer used in modern cloning techniques. After many debates over fraud and ethics, the Roslin Institute becomes famous for its scientists who created some of the most famous clones, including Megan and Morag, Dolly, and other sheep. The world of cloning expands with the discovery of new technologies, and the ethics debate increases as the possibility of human cloning is made more known through many known frauds and real experiments.

The concept of “cloning” is creating an organism with the same DNA as another. This means that the natural world has been creating clones for thousands of years. Such examples are identical twins and self-pollinated plants. However, artificially creating clones intentionally by nuclear transfer is, compared to the beginning of natural cloning, a recent human experiment. Although cloning has been extremely successful in this past decade, important concepts and large steps have been taken over the past century.
The first successful cloning attempt was performed by Hans Dreisch in 1894, who cloned a sea urchin by isolating blastomer...

Essay about Cloning Should Not Be Allowed For Medical Purposes

- ... This embryo is next placed in a surrogate mother, who will become pregnant with the cloned organism. Lastly, the surrogate mother will give birth to the clone, thus completing the cloning process (Cohmer 1). Furthermore, another method of cloning is called therapeutic cloning. This method is designed to clone a human or animal’s exact body parts, rather than entire organisms. In therapeutic cloning, scientists are able to make pluripotent cells, which can essentially treat diseases and replace damaged body parts (Perl 20)....   [tags: Cloning, DNA, Human cloning, Gene]

Essay about Cloning

- For the last few decades, cloning was a fictitious idea that lay deep within the pages of some sci-fi novels.

That fine day was February 22, 1997. A team from the Roslin Institute which was lead by Dr. Ian Wilmut changed the face of history forever by revealing what looked like an average sheep. That sheep was what was going to be one of the most famous if not the most famous sheep in modern day....   [tags: Biology Cloning]
