An analysis of the issues of cloning
The process involves introducing the nuclear material of a human somatic cell donor into an oocyte egg cell whose own nucleus has been removed or inactivated, and then stimulating this new entity to begin dividing and growing, yielding a cloned human embryo.
The process of extraction ruins the embryo and this issue creates a lot of ethical concerns. Females reduce the production from X-chromosome genes to the level seen in males by shutting down almost an entire X chromosome. Google Scholar Kolata, G. The only problem is that it might be banned as the point of prohibition. On the other hand, based on principle , constitution law, it is an unchangeable principle and it has been constant after all reviews. If yes, to what extent are they expressive and comprehensive and if not, what should be done against the practice and the perpetrators? Atrak H. Google Scholar Busch, L. Again, this strategy has not led to a solution to low cloning efficiencies. In some cases, progress has been made, but no clear picture has emerged, particularly when nuclear transplantation from adult rather than embryonic cells is used. Jongkamonwiwat N, Noisa P. That can happen naturally [ 99 ; ] and has been induced in humans with ooplasmic transfer [ ]; see Chapter 4. In conclusion, research into the science of genetic reprogramming and animal cloning is in its infancy, and much more information is needed. Could imprinting errors cause problems for the human mother?
Cloning has been used in various fields of biology while the DNA molecule of cells with genetically identical structure is known as a clone.
There are some other legal problems too.
Moral issues of cloning
Google Scholar Wilmut, I. In the future, new and improved methods of activation might allow the process to be controlled more precisely [ 1 ]. According to reports by Professor Hassan Javaheri, there is no problem on cloning happening in nature, but it is not legal to be undertaken at large scale. These form when an egg that lacks a nucleus is fertilized by a sperm, so that all the DNA is contributed by the sperm. Although in bioethical and jurisdictional point of view, the status of reproductive and therapeutic cloning is analyzable, and sanction is the legal status of the matter to be required and of great importance. Accordingly, change of creation is the temptation of Devil and Devil also tempts to corruption, prostitution and sins; thus, changes in creation is prohibited. The United Methodist Church opposed research and reproductive cloning in May and again in May One hundred or more genes might be imprinted in humans [ 58 ; 90 ]. To prevent from long-term culture of embryo and future abuse from it, the experiments will be done on embryos of less than day-old. Here is what every Christian should know about human cloning: What is cloning? Finally, several groups have tried the technique of serial nuclear transfer or recloning in an attempt to overcome both reprogramming and egg-activation problems. Some of these possibilities are listed below. But ultimately, a large number of the Muslim jurists considered it as the secondary prohibition despite its primary and natural permissibility. Currently, the primary justification for therapeutic cloning is as a means of harvesting embryonic stem cells. But when SCNT is performed, such compensation might no longer be present.

As part of this process, any persons advocating the practice of human reproductive cloning would need to acknowledge the extent of the abnormalities seen in animal cloning experiments and to demonstrate that these problems—assuming that they persist—are unlikely to occur in humans.
Cloning is achieved by a technique referred to as somatic cell nuclear transfer SCNT.
Psychological issues with human cloning
Despite such a wonderful role, whose aspects reveal development of scientific researches everyday, it is required that the jurisprudence has comment on the mentioned problem, the problem which is referred as the loss of ethical dignity and human right on the embryo. Participants in any human cloning research efforts require full protection as human research participants, although it should be noted that, as with fetal surgery, this protection cannot be extended fully to the cloned fetus. After carefully considering the issues raised, we conclude that the case has not been proved that human reproductive cloning would lead to fewer negative outcomes at this time than reproductive cloning of other mammals. Does cloning produce an exact genetic replica of the donor? This serial transfer does two things: it allows the nucleus more time to be exposed to egg cytoplasm for possible reprogramming, and in some cases it uses an egg that has been activated normally by fertilization. Thus, there is a potential for cloned embryos, with their chromosomes from somatic cells, to have shortened telomeres. Finding The science of cloning is an international one with research conducted throughout the world. For example, one problem may lie in the methods now used to activate the egg after nuclear transplantation.
If there is a problem, it is in the next stages which are not related to this stage. The regenerative effect of bone marrow-derived stem cells on cell count and survival in acute radiation syndrome. To prevent from long-term culture of embryo and future abuse from it, the experiments will be done on embryos of less than day-old.
What adds more complications to this subject is that: first, it is not certain that scientists achieve what they claim. In addition, because of the large number of eggs needed for such experiments, many more women would be exposed to the risks inherent in egg donation for a single cloning attempt than for the reproduction of a child by the presently used in vitro fertilization IVF techniques.
