Concept in Definition ABC

Is named Clone to the cell set u organisms that are genetically identical and that originated from reproductionasexual.
Cloning It is the name of the technique that allows such a question, of the reproduction by means of a single cell or organism, from the artificial division of initial embryonic stages.

Meanwhile, cloning is the production of a biological entity, be it a gene, a chromosome, a cell or an organism, from an existing one. Such a process can be carried out with hereditary molecules, that is, reproducing DNA obtained from the same initial sequence.

On the other hand, a vertebrate clone It is obtained by replacing the nucleus of an unfertilized ovum with the nucleus of an adult cell of the individual to be cloned. Such a technique was first carried out successfully in the middle of the last century, more precisely in the year 1950, being the frogs the organism that was used for the practice.
The cloning a mammalwould arrive later, in the year 1996, with the cloning of the

dolly sheep And of course, such a realization also came wrapped in scandal and controversy since it certainly opened the door to the next stage, which was the cloning of humans.

So human cloning still remains today debate, firstly, because of the ethical dilemma that it would entail and that even nowhere in the world have they been able to find a positive solution for it.
From a technical point of view, many assure that the conditions are already in place to give a such a fundamental step in science, however, doubts hover over two issues, on the one hand, the identity of the clones and on the other hand, the instrumentalization of humanity. Both issues are the two great obstacles that to date have ruled out the possibilities of human cloning.

In human matter there are two possibilities of cloning, the reproductive cloning (supposes the cloning of a human being completely) and the therapeutic clonation (The cells of an adult individual are cloned, so that in the future or when necessary, they are used by medicine).
