From the invisible to the visible world and back...

Today I will talking about a subject that draws my attention, this is the cloning, because in my opinion it is a technique very interesting.  Also, is a subject very controversial, that is why  from scientist and theoligians to radio announcers and lawyers have discussed the religious, ethical and legal aspects involved in the cloning of human being. It also reises questions about the manipulation of human beings for the benefit of others, our obligation to heal the sick ( and their limits), and the respect and protection we owe to human life.

The cloning is a variety  of processes that they can use for  to produce genetically identical copies of a biological entity. The copied material, wich has the same genetic makeup as the original, it  is know a clone.

Researches have cloned a wide variety of biological material, including genes, cells, tissues and even whole organisms, such as sheep. In fact, the first case of cloning was the sheep "Dolly", who was the first mammal cloned from an adult cell. Its creators were scientists at the Roslin Institute in Edingburgh (Scotland). His birth was not announced until seven months later, on February 22, 1997.
In our career it is very important, because thanks to this  is possible clone cells with the objective of try drugs in these. But, not only cells, because also of tissues or other microorganisms, it is possible clone in order to test many drogs. 
I learned about this subject, when I was 10 years old, in a moment that I watched T.V and "Salfate" speak of the cloning and  from there it called my attention. 
In future, the cloning can have uses unsuspected, because even  it would be  possible cloned humans in benefit of others. But, also would allow to conserve species in danger of extinction.

The advantages that this technique  could have are:

•  In case of human cloning, the ability to restore functions in organs with damage, for example neuronal regeneration.
• Breeding of species today. 
• Will allow to have children with the characteristics of only one the spouses, in the supposition that the other one suffered from a serious genetic disease not yet resolved.

And for last, the disadvantages could have are:

• Genetic manipulation supplanting the nature of things.
• The misuse, because could clone with objective of supplant other humans.
• Genetic diversity  would be lost.
