Human cloning

                Human cloning:-
Did not reach the flag and technological:
      Developments that we see today, but perseverance and scientific research and what we see today all the organs of sophisticated science and advanced the idea began to operate in the mind of someone and then developed by others and others that arrived today from what we see the reality was a day of days of pure Imagination and hope to become the idea of human cloning a reality someday solve many outstanding issues that had not reached medicine to solve what kinds of cloning, and its uses and its objectives???
Reproduction: 
Is the process of formation of a living organism using cells from non-genetic cells of the body and here we mean cell genetic animal sperm and egg, and this object referring be identical in terms of genes derived from animal cell physical and this operation is carried out following steps: --
 Somatic cell taken from the organism first place than any of the body and are emptied and the separation of these cell
nucleus containing genetic material of any full 46 chromosome.
 To be introducing the nucleus of being No. 1 within the circle of the egg nucleus of being No. 2 and after exposing them to shipments of electrical division occurs in the cell nucleus composed of Jenin again be a replica of being No. 1 in terms of genetic composition, but it is wrong to believe that this similarity is 100% because there is genetic material found in Almetukondria found in animal egg No. 2, which may change the composition of the new organism and make a difference when simple.
What about human cloning???



These operations are still currently very limited because of government restrictions on such research because of their problems threaten human generation since most tests in the area failed and they need to finance significant material and high-level expertise in that 90% of the tests fail to Composition of Jenin, more than 100 cell nucleus transfer process may require the composition of Jenin and a successful one.
  . There are also other impediments to this research, including animals that formed through cloning suffer from serious weaknesses in the immune system, and also the speed of infection, especially oncological malignancies and other diseases which affect the nervous system and believed that there were problems in the mental aspects, which proved difficult for cloned animals For lack of need for mental capacities such as human as well as some researchers have found in Japan that live animals reproduced the situation of poor health and many of them suffer sudden death.
     And it is worth mentioning here that an international Dolly was killed in February 2003 after being infected needle particularly lung cancer and severe disability and acute arthritis age 7 years despite the fact that their peers have reached the age of 11-12 years and after the autopsy found free of any problems except for cancer Lung and arthritis.
 . Each result of the foregoing it is necessary to take drastic measures to prevent such conduct experiments on human beings and have been issued strict laws in most countries of the world including America, Europe and Japan to ban such tests.
  Applications of cloning for infertility treatment: --
   -- From modern applications of cloning is the process toward so-called genetic material (Haplodization) and by taking the nucleus of the cell physical condition and the first animal genetic material in special ways to become a chromosome containing 23 eggs and merged to become the second animal cell formed on chromosome 46 of the first half Animal 1 and the second half of the animals 2 and is very similar to the natural fertilization process.
   -- Other therapeutic method is the use of the sterility of stem cells, and here the goal is to reach a cell genetic animal sperm or egg of these stem cells.
  . Steps began this research develop multiple types of these stem cells and then you take the group that began the shift to the cells and the nationality of this group continue to grow brands in the fabric is taken from the ovary and testis or have been conducting this experiment on the laboratory mouse, and after 3 months, began Animal sperm are fugitives.
    And benefit from this type of testing patients exposed to chemical treatment with stem cells are frozen animal sperm before starting treatment and then be re-cultivated in the testis after the completion of the treatment programme.
   And as is the case for the production of Sperm it is possible to produce eggs the same way.
  And come back and say that the ideas evolve and succeed, perseverance and the great tree began stub and may become a problem of infertility, which read a lot of couples have problems simple and easy and becomes every couple of great hope in obtaining child Jamil Saad approaching this problem and the sad end of the Valley A .bright future, God willing .
