The cloning


What is cloning?
What is the process to cloning ADN?
What is the next step in clonation?
What the scientist think about the human clonation?
What are some aplication of cloning?
What do you think about cloning?
If you could cloning people would you do?
Why?


Cloning can be defined as the process by which identical copies are already developed a body, so asexual. These two features are important:

§ It is part of an animal and developed because cloning responds to an interest in obtaining copies of a specific animal that interests us, and only when adults know their characteristics.

§ On the other hand, it is asexually. Sexual reproduction allows us to get identical copies, as this type of reproduction by its very nature generates diversity.

REPRODUCTIVE CLONING
Reproductive cloning aims at obtaining adult. As we have explained, reproductive cloning has been successfully tested in various mammals. Human reproductive cloning has sparked strong opposition by almost the entire scientific community and institutions in the world. Only a few scientists (Dr. Davos in the U.S. and Dr. Antinori in Italy) were in favor of obtaining adult human beings by cloning, despite harsh criticism from all areas.Just as U.S. sect, led by Rael, were interested in cloning 'the messiah', child of 10 months and cryopreserved died years ago and say they have already raised enough funds to begin cloning a human being.

Ethical issues of cloning
The donation raises interesting expectations, and ethical issues in society and in the scientific community, where there are areas for the use of these techniques and sectors against. In Spain, scientists of the Expert Committee on Bioethics and Cloning, expect for a few more years will not be possible to implement safe techniques of donation, and discard, for the time being any possibility of donation of human beings, limit the use of these techniques to the treatment and cure of genetic diseases, the creation of new drugs, thanks to transgenic animals, and the conduct of xenotransplantation, ie transplantation in humans of organs from animals with a very similar genetic makeup, asthe pig. In this forum we discuss the irresponsibility that would currently applying these methods of donation in humans. It is certain that children could be developed through these techniques presented deformations, such as two heads, two hearts, no hands or feet or an abnormal number of limbs. Themselves "fathers" of Dolly the sheep suggest the chained series of genetic disorders that might arise: genetic codes that identify serious disorders, how, premature aging, cancer and neurological diseases about which there is, today, accurate knowledge.
Ethical problems arise around the issue of accessibility to these techniques by influential people with large ECO3 nomic resources, which could use this scientific instrument as a tool for its own perpetuation. In the case of animals, has raised the possibility of creating populations that although humanity may offer higher quality products would be completely homogeneous and could die very easily to an epidemic.Currently used in transgenic animals, thanks to the techniques of donation, would be an inexhaustible source of organs for human transplantation. On the other hand, although their achievement is fictional, these species could be used to treat many diseases in humans.
