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. Some may think of cloning Einstein or Usain Bolt and give rise to a league of superhumans or super-sportsmen. The science of cloning is unsuccessful a majority of the time. Therefore, pursuant to ethical principles and potential risks of cloning operations, further contemplations are needed on the technology and it should be avoided at least until its hidden aspects are clearly revealed. Gene diversity is what keeps an entire species from being wiped out by a singular virus if none of them have natural immunities.
Scientists around the world continue to argue the advantages of cloning in hopes of being able to research it more thoroughly, but more than 30 countries have already issued bans on human reproductive cloning. However, he allowed human cloning in rare cases and necessities when it is beneficial for human health and also the use of its scientific aspects; such as the cloning of organs for treatment purpose. Now to review the three stages: The first stage is the use of the cell from human body which is automatically not objected. The process is quite similar to the process in which identical twins are born. Surrogate Mothers Suffer In order for these clones to be born, they have to be carried to term by a surrogate mother animals. Each cloned baby would be cherished, but why? Scientists need a lot of plants and animals to conduct their researches; when these plants and animals are available as clones not only these plants and animals are saved but scientists can have as many species of clones as they need for the purpose of experimentation.
For example, Ayatollah Sistani and Ayatollah Fazel Lankarani considered human cloning not to be problematic if is limited to reconstruction of tissue damages. The first issue is the destruction of the initial embryos which is considered as disrespect of the newly-reproduced human and the initial point of human life. Children would still be in abusive situations. Single-cell organisms like some yeasts and bacteria naturally reproduce clones of parent cells via budding or binary fission. Though cloning animals might sound amazing on films, it still remains experimental with a lot of limitations in the real world.
It can help in the production of proteins and drugs in the field of medicine. A lack of genetic variation creates a reduced resiliency for the offspring in that species. This idea and the probability of its occurrence have revealed the lawful Iranian responsibility more than before and showed the necessity of taking immediate action to fill this legal gap. In regard to consent of the cloned child, the consent and permission of the donor of oocyte, the pregnant mother and even the donor of the somatic cell are also considered and it is an issue which can be harassed and abused. Irrespective of whether it is human reproductive cloning or therapeutic cloning, the pros and cons have to be taken into consideration when trying to determine whether the process is safe or not.
Cloned plants are used on a large scale to beautify the environment and the plants grown from cuttings are also clones because they are actually genetic copies of the original. The first cloned animal from an adult somatic cell was Dolly the Sheep, a process which was successfully completed in the 1990s. The end result would not be a human being, but rather a piece of nerve tissue, replacement organ or quantity of skin. A has given a green label to cloned meat. The success stories of human cloning and creating tissue cells have come from different parts of the world. The process of extraction ruins the embryo and this issue creates a lot of ethical concerns.
Naturally, there is a difference between the three categories. But does anyone really believe that scientific ethics are enough to restrain the scientific community, one that is often controlled by a profit motive, from moving closer and closer to cloning? In 1885, Hans Dreisch became the first person to successfully perform a cloning experiment with a sea urchin. If a clone is an exact replica of the host, then embryos could be implanted with the sole purpose of helping with the health of the host instead of treating the clone with equal rights as a human being. It is a new world of science that is still continually be discovered. For people who support human cloning, if an unborn child will be diagnosed with genetic defects, healthy cells can be cloned and be used to replace the defected genes of the fetus. Under this technique, the nucleus of an egg cell taken from a donor is removed.
What started off as a major achievement in the field of biology, has of late become one of the most controversial issues in the world. This means this procedure would lead us to extinction. Not to mention that it would eliminate surprise and predict expectancy. The most important organs of the human body can be cloned and kept intact so as to be used in cases of emergencies, like when the real organs stop working. Those who support animal cloning argue that this scientific process provides a solution for conserving and preserving animal species. Also, there are insufficient renal development, hernia and a few other conditions. Also, while Dolly was a successful clone, there were hundreds of failed clones before she was made, including several dead fetuses.
Scientists are still unsure of any genetic mutations that might occur when an animal is cloned. If the reasons aren't ethical, then you've got a problem. The first clone, Dolly the sheep, born to a surrogate in 1996, was a genetic copy of a six-year old sheep. Plants and animals have already been successfully cloned, but the next step is making many people uncomfortable, human cloning. The respect to human dignity is in a manner that it is highly considered in the international rules and declarations; for example, in the introduction and some of the articles of International Declaration on Human Genetic Data, 2003, observing the human dignity is a must and also the first article of International Declaration on the Human Genome and Human Rights, 11 November 1997, the human genome is considered as part of human heritage and it declares that human genome is the principle of fundamental unity of all members of the human family and the need for recognition of their inherent dignity and distinction and the article 11 of the declaration knows the human reproductive cloning in contrary to human dignity.
It would be an easy way to solve the organ scarcity issue that currently exists. This BiologyWise article on human cloning will cover the advantages of cloning humans. The United Nations estimates that more than 10 billion people will populate the planet by the year 2050. However, many countries and governments have banned human cloning fearing the ill-effects of human clones. But with cloning, parents involved will tend to only value their children according to how much they look like themselves. This results to a significant difference on the cell makeup between the replicated and original organ.
Artificial animal cloning involves gene cloning, therapeutic cloning, or reproductive cloning. Cheetahs, for example, share 99% of their genetics with other members of their species. Sheep cloning from embryonic cells was performed in 1984. Even today, veterinarians are offering the option of freezing small tissue samples from a pet that has passed away in case animal cloning becomes mainstream. With the process involved in human cloning and the controversial issues that go with it, more time will be needed until its realization. And by cloning animals, the problem with the shortage of protein sources, as well as vaccines that are derived from animals, can be resolved.
