Cloning for medical purposes has the potential to benefit large numbers of people. The Pros of Human Cloning Here are the primary benefits to the science of human cloning: Defective genes could be eliminated. As an example, scientists could take cells from a cow that produces large amounts of milk and grow them in culture. It is a new world of science that is still continually be discovered. In 1997, the National Bioethics Advisory Commission recommended that it was morally unacceptable to attempt to create a child using somatic cell nuclear transfer cloning and suggested that a moratorium be imposed until safety of this technique could be assessed. The entire world would be changed if we began to clone humans, in some ways for the better, but in others it would be much worse. Even if we regard the growth in modern science and technologies to have reached its peak, health risks of cloning can't be denied.
In return, however, the advantages of cloning are also quite apparent: human cloning could very well lead to faster medical cures, a better overall quality of life, and even longer life spans. The Catholic Church has taken a definite stance against cloning and asked for stricter regulations for such technology. On the other hand, embryos are considered much applicable in disease curing and most of the research should be done on them instead of adult stem cells. Even when medical science reduces potential risks of cloning to minimum, which is possible, given the billions of dollars put in cloning research, ethical issues regarding cloning will always haunt us. Medically, it has raised some prominent questions regarding health risks of cloning. With cloning, there is a real possibility that humans would become more of a commodity than an individual. Not only researchers but even common people became interested in knowing about how cloning is done and what pros and cons it has.
When scientists looked at the telomere lengths of cloned animals, they found no clear answers. The dangers of human cloning were dramatically underlined yesterday. Though human clones would be a brand new set of life with unique preferences, a loss of individuality is still potential, as clones would be simply twins of someone else, regardless of the age of that other person might be. Proc Natl Acad Sci U S A. Also, the implications of what happens when the process goes wrong are still not fully understood, which is not good and could lead to problems that we will not be able to handle. The shift toward using this technology for the benefit of mankind rather than controversial experiments has happened in the last decade, and the world now awaits the next breakthrough. Dolly is different because she is not genetically unique; when born she was genetically identical to an existing six-year-old ewe.
When we hear of cloning successes, we learn about only the few attempts that worked. Programs are underway to clone agricultural animals, such as cattle and pigs, that are efficient producers of high-quality milk or meat. This can effectively interrupt metabolic activities in the clone and cause critical organ failure and death. When it comes to infertile couples, should not they be granted the opportunity to produce clones of themselves? The older the animal is, the shorter its telomeres are, because the cells would have divided many times: This is a natural part of aging. Professor Wilmut says the ban already in operation in Europe and the U. The difference though, is that the birth of identical twins is a natural process, while what we refer to as human cloning is an artificial process. Let us take a look at the pros and cons of cloning humans to come up with a well-informed decision on our end.
Much of it relates to helping human families gain children, but there is also a benefit for the animal world. This would be done with the technology of human cloning, and could prolong the average life span of a human being dramatically. However, is it really an option that should be considered as a way to extend human life? Using their own cells, they would be given the chance to truly heal with less complications. While the debate about cloning humans is ongoing, how do you feel about it? A calf cloned in France did well for several weeks but died suddenly at 51 days after its ability to produce white blood cells failed. Though in the beginning it was believed that therapeutic cloning will be helpful in curing the diseases, but as the application of adult stem cells is limited that is why this type of cloning is not giving the results which scientists want. Telomeric differences As cells divide, their chromosomes get shorter.
The risks of human consumption are not yet clear and there are fears of it escaping and breeding with natural salmon. H igh failure Rate Cloning animals through somatic cell nuclear transfer is inefficient. Cloning can make it possible for us to obtain customized organisms and harness them for the benefit of society. But when it comes to humans, ignoring the 'human aspects' can be a big mistake. While the cloning of non-mammals has occurred in research contexts for many years, the cloning of the first mammal, Dolly the sheep, surprised many in the scientific community. There also exist concepts such as replacement cloning, wherein a clone of previously living person can be created, and persistence cloning, wherein the cloned body will be created to do away with the process of aging.
We will ensure that it reaches to millions of people across the globe. However, cloning their own cells can lower recovery time and true healing could occur. Reproductive cloning is becoming unpopular due to its complexity and failure rates that are way beyond what can be termed economically feasible. Data from these experiments illustrate the problems involved. Some scientists believe that the cloning process can turn any gene on or off at random, with unpredictable and potentially devastating impact on the health and even behaviour of a human clone. But some scientists are sceptical about his assertions.
Because an older cell is often being used to create a human clone, there is the possibility that this imprinted age could be placed on the growing embryo. And once techniques become more streamlined and efficient, they fear that some may be tempted to take that next step. The fact that the laws are divided on such a sensitive issue is a certain feature of potential trouble. What laws would there be to defend your rights as the true non-clone compared to the clone? Medical Issues Human cloning can give rise to certain medical issues. Final Note Whatever your view on cloning may be, studies show that the clone would in fact not be completely identical to the original just as twins are not completely identical. One gelded racing horse, a male whose testes have been removed, has a clone that is available for breeding.
