Cloning , the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination.
Dolly the sheep, the first mammal cloned from a somatic body cell, came into the world innocent as a lamb. However, soon after the announcement of her birth in February Wilmut et al.
About Map Blog Contact. Human cloning could lead to medical advancements. The Pros of Human Cloning. Approximately 1 in , people in the U. Although ethical issues stand in the way of cloning full humans, other animals, like sheep, rats, cats, dogs and even monkeys have been cloned. The bucardo, an extinct wild goat, only lived for about 10 minutes after it reached a stage of meaningful life. Stem cells divide quickly, and scientists worry the cells could change after implantation into the patient, possibly leading to cancer or uncontrolled cell growth.
I think nobody can afford to ignore the progress that is made in science today. Scientific research gives us knowledge about things that nobody ever thought about just a few years ago, for example the cloning of humans. In this essay I want to focus on this topic with special regard to the advantages and disadvantages and the social and ethical problems. I will start with a definition of cloning. The next part of the essay will be about the beginning of life followed by a listing of arguments about advantages and disadvantages of human cloning. Furthermore my essay will involve a look on cloning and sciene fiction and finish with the economic reasons for cloning humans.
Handbook of Global Bioethics pp Cite as. This chapter covers the technical, philosophical, and juridical aspects of international governance of human reproductive cloning. Human reproductive cloning is the creation of a human embryo from a nuclear DNA sequence of an existing human being or from one having existed earlier in order to implant it into a womb, leading eventually to the birth of an identical human being. The methods available for cloning are developing quickly, and first the principal technical approaches to this issue are described. Then the main arguments used in the ethical discussions over human cloning are presented, both supporting and opposing it.
Society is much more relaxed about the idea of cloning plants when compared to cloning animals. Some people see this technology as way to mimic natural processes since an identical twin is essentially a clone that happens thorough natural reproductive methods. Dolly the Sheep was a successful experiment because scientists found that they could produce offspring from an undifferentiated cell through nuclear transfer. We have used this method to improve the animal cloning processes for other species, but the cost of following this process for commercial purposes is still way too high. When we examine the advantages and disadvantages of cloning animals, we must balance the need to push evolution along while still providing diversity in genetic structures. We already know that entire monocrops get wiped out when disease impacts agriculture, so the same outcome is quite likely when we take the same approach with the animal kingdom. Cloning animals would allow us to balance environmental habitats.
20 Advantages and Disadvantages of Cloning Animals
Human cloning is the creation of a genetically identical copy or clone of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins. The possibility of person cloning has raised controversies. These ethical concerns have prompted several nations to pass laws regarding human cloning and its legality.
As far as anyone really knows, scientists have yet to clone a human being, and there are no federal laws against it in the United State. However, seven states prohibit it altogether, and 10 states only allow it for biomedical research. While more than 30 countries formally ban cloning for reproductive purposes, China, England, Israel, Singapore and Sweden do allow cloning for research, but disallow reproductive cloning. The definition of a clone as explained by Encyclopaedia Britannica is a cell or living thing, an organism, that is "genetically identical to the original cell or organism" from which it comes.
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, the countries of China, Sweden, England, Israel and Singapore do allow cloning for reasons that have nothing to do with human reproduction. Some of the pros of cloning include recreating livestock, deceased pets and bringing extinct species back to life, but arguments against cloning mostly focus on human cloning for reproductive purposes.
The Cons of Cloning
Поверь. Поэтому я и узнал о его намерении модифицировать Цифровую крепость. Я читал все его мозговые штурмы. Мозговые штурмы. Сьюзан замолчала. По-видимому, Стратмор проверял свой план с помощью программы Мозговой штурм.
Беккер терпеть не мог говорить с автоответчиком: только задумаешься, а тот уже отключился. - Прости, не мог позвонить раньше, - успел сказать. Подумал, не рассказать ли ей. Но решил этого не делать.
Но, сеньор, она занята с клиентом.
Согласно регистру, кто-то открывал ее компьютер, пока ее не было в комнате. Но это невозможно. У нее перехватило дыхание. Единственным кандидатом в подозреваемые был Грег Хейл, но Сьюзан могла поклясться, что никогда не давала ему свой персональный код. Следуя классической криптографической процедуре, она выбрала пароль произвольно и не стала его записывать.
Но Стратмор ее не слышал.
И долго ты собираешься здесь сидеть. - Всю ночь, - безучастно ответила Сьюзан. - Хм-м… - пробурчал Хейл с набитым ртом.
Других слов для него у нее не. Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо.
Я надеюсь, что ты мне все объяснишь.
