During look-alike of John F. Kennedy Jr. could


During my interview with my grandmother I asked her what she thought of cloning.she responded by saying that it was not right and should be stopped. on theother hand i have a different opinion. I think that cloning should be continuedand furhter researched for we might be able to have different organs andsubstances produced in these clones. Below is the step that were taken to clonethe adult sheep named Dolly.

Part 1: An Improbable Goal Scientists hoped thatcloning healthy, mature sheep, rather than just creating lambs from embryoniccells, could produce a highly specialized sheep with large quantities ofproteins in its milk. The proteins are believed to help treat diseases such asemphysema, hemophylia and cystic fibrosis. Part 2: The Perfect Timing For years,scientists could not synchronize the growth of the egg and the cell. If one wasoff- synch, abnormal chromosomes would soon transform in the nucleus and therebykill off the embryo. Dr. Wilmut achieved near perfection in the timing byputting the cells into hybernation; of the 277 eggs they began with, 247 livedthrough the process.

Timing the growth in other species, however, has proved toscientists that cloning mature animals is extremely difficult; in the case ofmice, they’ve concluded it can’t be accomplished. Part 3: Jump-start from a JoltThough it has become a standard procedure in cloning, scientists are not surewhy an electric pulse sent to the two cells causes them to meld together andactivates development in the egg. They are learning, however, the shock doesn’tfully mimic the activation process of a sperm, which could explain why just 29of the remaining 247 cells live longer than six days. Part 4: SurrogateMotherhood Despite the fact that the newly formed embryo is transplanted intothe uterus of another ewe, scientists believe Dolly is a nearly exactcarbon-copy of her genetic originating mother. In theory, that means an almostexact look-alike of John F. Kennedy Jr. could be produced by taking cells fromhis skin, melding their nuclei with any woman’s egg that has had its nucleusremoved and then planting the embryo in a surrogate mother.

Part 5: A 6-Year-Oldin 7 Months? Scientists are eagerly watching Dolly to see if she exhibits thecharacteristics of her mother, a 6-year-old sheep, or those of her own age, just7 months. As animals and humans age, changes occur in their DNA – such asdecreasing fertility and increasing susceptibility to cancer and other diseases.If she prematurely ages, clones of mature animals would be useless to theagriculture industry.Science

Cloning and quest for information. Now as


CloningFor the better part of scientific research history, animals have been used to facilitate the testing of new procedures, drugs, and quest for information. Now as we enter the 21st century humanity has created computer prediction models, tissue cloning, and great understanding of chemical reactions. However most of these new methods still are only sparingly used, despite their accuracy, and animal testing still remains the test method of choice. Imagine the world where everything was doubled, or tripled. Theres a newly developed technology that can allow doctors and scientists to duplicate living organisms.

This development in technology is known as cloning, and it has forever changed the views of life. Cloning can serve as the answer to problems which plaque the human, animal, and plant populations. Any living species can now be artificially created through cloning. This could potentially eliminate the possibility of extinction among many species. Cloning creates the possibility of having a twin or child carrying the exact DNA of another person. The reproduction of animals would ensure the lasting life of all species, and produce an abundant amount of food to feed the people of the world. Even the vegetarians of the world would be happy with the amount of vegetation that could be produced. Cloning is the perfect means of improving the quality of human life on this planet.

Cloning is a very controversial topic and will be for many years to come. In February 1997, scientists in Scotland announced the birth of Dolly, the first cloned sheep. This heralded the future of further cloning possibilities and scientists began extensive experiments on cloning, and have since cloned both plants and animals successfully.

The next step was to clone actual human beings but before experiments could be carried out, pressure started to build on the scientists because people started to doubt if cloning was ethical and morally correct. The government began to ban and impose constraints on cloning as a result of public pressure. After the cloning of Dolly, President Clinton was quick to cut all federal funding for research of human cloning (Lester & Hefley, 123). In December of 2001, the United Kingdom put a ban on human reproductive cloning but not therapeutic cloning (Seppa, 32). Even though cloning raises some difficult ethical issues, there are many aspects of cloning that will be very beneficial to mankind.If the experimentation of cloning continues in the United States, scientists have the ability to clone body organs that could replace a persons damaged organs. This would prove to be most helpful for organ transplant patients.

Doctors and scientists would be able to clone an existing kidney, which would create the possibility for a fully operating organ to be transplanted into a patient rather than from a donor. Cloning has implications for conquering diseases such as Parkinson’s disease, cancer and many other major deadly diseases. Cell-based therapy with the fusion of a single nucleus to an egg can treat certain diseases (Andrews, 87). Researchers have found that heritable diseases cause a lot of early deaths in many Americans. On average, two million Americans die each year and the statistics show the impact. 750,000 die from heart diseases, 500,000 from different types of cancer, and 150,000 die as a cause of strokes.

Approximately 70% of these deaths are related to genetic conditions that may have been prevented (92). Using cloning to save people from their failing organs and genetic illnesses would benefit many by giving them the opportunity to live healthier, longer lives.There are millions of Americans living today with many of these mentioned diseases. Those with objections to the use of cloning to better these peoples lives obviously havent put themselves in the position of anyone who could potentially be saved by these new techniques.These medical techniques cannot only be used to benefit humans, but animals may be able to be saved as well. Full animal cloning could be used to increase the population of endangered species of animals, and thus save them from total extinction. This would help maintain a natural balance on the earth and have a continuous natural life cycle.
