Cloning can be defined as the process by which asexually get identifical copues of the Agency of the United
Nations and developed.
Why is cloning possible?
The possibility of cloning was raised with yhe discovery of
DNA and the knowledge of how it is transmitted and
expresses genetic information in living things. To better
understand this need to briefly recall how is made a living
being. A particulr animal is made up of millions of cells,
which are like the bricks that form the building that is the living being. These cells have very different aspects and funtions. But they all have one thing in common: in their cores have a long chains containing accurate information on how the body is organized: DNA each cell contains all the information about how and how the whole organism develops part. The creation of a human embryo by cloning has generated all sorts of reactions and comments from unfounded to falsely reassuring.
First, compared to the average truth (Half lie) that had produced embryonic stem cells, reality (as reported in Digital Protestant from the first moment) is that a human embryo is created whose growth stopped to take it embryonic stem cells containing. We try to answer some of the questions raised.
What is a human clone?
The creation of a human embryo by cloning has generated al sorts of reactions and comments from onfounded to falsely reassuring.
Simplifying without falling into the false, we can say that a human clone is equivalent to artificially prodece something similar to what happens to an embryo splits naturally into two twins.
Two dofferent human being are generated even come from an identical genetic content (Thare is always then small changes during development).
That is, everyone has their own identity, soul and spirit (do nt enter into theological and psychological issues) that troughout his life kept aganinst his twin. No twin, but with special ties, have identity problems regarding known him against the other albeit almost identical in appearance. The personality of each individual is formed by the interation with the environment.
You can not exactly reproduce all environmental condictions that have influenced the life of a person to make any genetically identical to ist parent clone also had the same character, the same attitude towards life, continually take same decisiond or use his free will in the sawe way.
The controversy surrounding the issue revolves around different issues. The main issue is the use of embryos to extract stem cells, is an embryo a human being? Since when an embryo or fetus should be considered human? On the religious side views it indicates that cloning is "playing God". On the social side it is "a human being created exclusively for the benefit of others."
Proponents indicate its advantages: it is a technique that can fight aging, heart problems, infertility and even cancers. They can also argue that human cloning can be used to generate tissues in order to rebuild the skin or replace defective organs.
The religosas institutions focus on ethical issues: is this cannibalizing embryos, it would exploit women for eggs, would be a more business. Remember the necessary attempts to clone Dolly (227) sheep and alternative methods for obtaining stem cells.
According to the Chinese company Boyalife, technology is advanced enough today to get the perfect cloning of human beings and animals.
According to the scientist and director of the Asian industry, Xu Xiaochun, in 2016 the city Tianjin, north of the country, will host a major center of genebank, capable of holding up to 5 million samples frozen in liquid nitrogen cells.
Xiaochun said that the company is not performing activities of human cloning times to avoid possible adverse public reaction.
Advances in cloning
Advances in cloning techniques now allow not only get clones of cells or tissues but also individuals. In February 1997 was unveiled with great folds in the media, birth, at the Roslin Institute in Edinburgh, Dolly the sheep, the first clone obtained from differentiated cells of an adult animal. This rekindled the controversy about the limits of scientific and technological research and the need to establish standards on bioethics, because if it was possible to reproduce a mammal, likewise be feasible to consider the cloning of human beings.
It was published in January 2000 by scientists at the University of Oregon (U.S.A.) the successful cloning of a rhesus primate through a different Dolly the sheep, consisting of dividing an embryo in its early stages of formation technique.
In December the British House of Commons approved, for the first time in Europe, the cloning of human embryos for medical purposes, prohibiting replication of people, this therapeutic cloning aims to get mothers cells capable of becoming body tissues. Research on cloning, applied to humans, offer significant hope in combating various diseases such as Parkinson's or Alzheimer's. Besides the cloned cells from the patient himself, avoid the rejection of transplants. For those opposed to the measure, it is ethically reprehensible create beings to heal others.
