The Cloning.
What is?
* It is a process by which one or more individuals obtained from a somatic cell or the core of it.
* The new individuals are genetically identical to the donorperson initial cell.
What is the procedure?
* Take a DNA fragment containing the gene.
* Insert the fragment in another molecule called DNA vector.
* DNA Recombination.
* Bringthe vector into a host cell to reproduce with DNA and recombined.
Historical background of cloning.
* Cloning from embryonic cells.
were thought to be the only ones capable ofgiving rise to any tissue type.
The cloning experiments were subsidized beef producers, who hoped that his "animal star" was cloned to increase their profits.
By this method itwas possible to clone sheep Megan and Morag, giving rise to continue scientists interested in the subject.
Cloning from stem cells.
1996
Dolly the sheep was born, the best known caseof cloning in animals.
It is the first to be cloned from mature cells specialized and mammary gland of another adult sheep.
Cloning in humans.
From animal achievements suchknowledge transfer attempts at human cloning.
The development of embryos in vitro allows obtaining undifferentiated progenitor cells can be induced to transform into the desired tissue.
Andall this, what is the goal?
Having a great number of clones of cells that can replace those damaged tissue or organ.
Advantages of the procedure to society.
Use the procedure aspart of therapy.
Treatment of diseases so far incurable.
Reproduction.
Transplants (increased compatibility).
Disadvantages of cloning.
Loss of the main characteristic of thehuman race be unique.
However ...
Remember that in the formation of the personality involved other external factors such as environmental influences, personal experiences, etc..
