About the method of cloning

 

Every day our world is improving. There are more developments in new fields of science, and as a result of this there is a significant amount of controversy and discussions on the topics discussed. One of the most striking examples we can think of recent achievements in the field of cloning, has generated a lot of questions. On the one hand, such discoveries are a huge step forward for fundamental science. On the other hand, there are moral problems associated with the ethics of human cloning.

The possibility of using this biotechnology to man became real only after the first positive results in animal cloning. One of the latest achievements of the method of cloning is creating a genetically identical objects obtained using the method of “replacement of the cell nucleus”. The essence of the method lies in the fact that from the cell nucleus, equipped with paired chromosomes, is transferred into an unfertilized egg, from which was removed before the parent kernel. The resulting embryo “ripen” for several days, after which normal developing embryos implanted to surrogate mothers. “Using this technology was obtained in 1996 the world-famous Dolly the sheep”[1]. Dolly, the famous sheep clone lived for 6 years and gave birth to 5 healthy lambs, but died of lung cancer that is quite common among sheep. It is believed that a possible cause of premature death was that her genetic age was only 6 years old.

Currently there are two types of cloning: reproductive and therapeutic. “As a result of reproductive cloning produces a new holistic organism that is a genetic copy of another organism is the clone”[2]. Actually the clone is just an identical twin of another person, delayed in time. However, sci-Fi novels and movies have created people the impression that human clones would be mindless zombies, monsters like Frankenstein or the twins. And all of this is complete nonsense.

Clones of humans are normal human beings, just like you or I, not zombies. They will bear an ordinary woman for 9 months, they will be born and will grow up in a family like any other child. They will need 18 years to reach adulthood, just like all other human beings. Consequently, a clone-twin will be decades younger than her original, so there is no danger that people will confuse the clone-twin with the original. Just like identical twins, the clone and DNA donor would have different fingerprints. The clone will not inherit anything from memoirs of the original individual. Due to all these differences, a clone is not a copy or counterpart of a person, but merely a younger identical twin. Human clones will have the same legal rights and responsibilities as any other person. Clones will be human beings in the fullest sense. You will not have the right to keep a clone as a slave. Slavery people been banned in the U.S. in 1865. Many people ask: "why clone humans?" There are at least two reasons: to provide an opportunity for families to conceive children-the twins of prominent personalities and to allow childless couples to have children. Living in free society, we must also ask the question: "whether the negative consequences are so inevitable that we should deny adults, acting voluntarily?" We will see that, in General, negative effects are not so insurmountable. And human cloning is a predictable methodology, consisting in the creation of the embryo and subsequent growth of the embryo of people with the genotype of an individual, now existing or previously existing. We learned that reproductive cloning can be called a process of cell reproduction, which does not stop at maximum 14-day period. The embryo moves into the woman's uterus, where it continues its development into a fetus and then a child. Therapeutic cloning is “cloning technology for the purpose of obtaining embryonic stem cells for scientific research”[3]. Supporters of human cloning believe that the development of this area will enable infertile people to have children of their own. We believe that this argument has special significance in many aspects. This conclusion is the rationale of the research results Kazakh doctors that “woman is the cause of infertility in marriage in 40-45% of cases. Male is 40%, both husband and wife are at 20-30% ”[4]. In addition to infertile couples, thanks to cloning technology, would also get the chance to have biologically related children couple non-standard orientations, which are not able to have children through sexual intercourse. Another very important positive factor in cloning is “the ability to grow parts of the human body, using the DNA of the host”[5]. If the man lost a child, close person or a loved pet, he can recreate it in the form of a clone. There is also the prospect of cloning outstanding people of the past: scientists, political leaders, athletes, movie stars. Another positive aspect of cloning is the ability to carry out the correction of injustice [6].

Obviously the cloning of humans has tremendous potential, but forget about the presence of negative consequences should not be. Development of culture and scientific progress, the clones would take a serious leap.

The United Nations called upon member Nations to enact laws banning all forms of cloning. In Kazakhstan, the country where we live, any form of cloning is prohibited by law. However, Belgium, Britain, Japan, South Korea, Russia and several other countries left the issue of therapeutic cloning to the discretion of individual States. We believe that the adoption of such a solution is justified by the fact that obtaining stem cells is of great importance in medicine for the treatment of various diseases.

In September 2008 the Australian government issued the license allowing scientists to create cloned human embryos to obtain embryonic stem cells. Contrary to popular belief, the clone usually is not a complete copy of the original, because when you clone you copy only the genotype, but the phenotype is not copied. Moreover, even if development under the same conditions, cloned organisms are not identical, because there are random deviations in the development. This proves the example of the natural human clones – identical twins, which usually develop in very similar conditions. Parents and friends can distinguish them by the location of moles, small differences in facial features, voice and other characteristics. They do not have identical branching blood vessels, is also not completely identical to their papillary lines. It is obvious that human cloning has enormous potential benefits and few possible negative effects. As with many scientific achievements of the past, such as airplanes and computers, the only threat is the threat to our own narrow mental complacency. Clones man can make a great contribution in the field of scientific progress, and cultural development. In certain cases, where are anticipated to possible abuse, they can be prevented by narrowly specialized legislation. With a drop of common sense and reasonable regulation, human cloning is not something to be afraid of. We should expect it with exciting anticipation, and support research that will accelerate the implementation of cloning. Exceptional people are among the greatest treasures of the world. Human cloning will allow us to maintain, and eventually even recover these treasures.
