    A Virus is an organism that attaches itself to healthy cells in a living organism,multipying in numbers and destroying healthy cells in the process.

    A virus is a microscopic organism Created mainly of nucleic acid surrounded by a membrane protein, which is a parasite living inside the cell to ensure his breeding, and most viruses cause disease in varying degrees of severity. Multiply viruses quickly by doubling Alkhiet nuclear DNA, and constitute Alinkliosedat the most important raw materials for the production of copies of DNA, but when you change these Alnichaeliosedat or modify the enzymes that enable the doubling of DNA do not recognize it and therefore will not be this process will not be getting new viruses, and in the seventies enabled amendment of Nichaeliosedat fight certain diseases, viral antigens were detected following the example experiment conducted on cancer cells at the end of the forties, which adopted the same principle. Thus has been the choice of many natural molecules and their derivatives by accident where shown some ability for anti-virus. But scientists and researchers think about the deliberate action rather than relying on chance and luck, because the development of scientific knowledge enabled the sequence of the protein and the active space for many of the viral proteins and compared with the previously known proteins, which authorized the anti-workout proteins known viral proteins detected. Has been to facilitate the search and give a more systematic, when used sophisticated IT systems that use software to study viral proteins, classification and help to propose potential antagonists. Projects preparation of viral antigens Scientists were able to learn about different varieties of viruses this organism, as identified on the stages of life and reproduction for each class, and combine these stages in the trunk of a common, although there are minor differences, since the virus generally grows through three stages: Entry into the target cell. The production of cell elements necessary for viral replication. Exit viruses sons after receiving the components produced by the cell. In order to eliminate the virus must work to find antioxidants work to stop the growth of the virus in one of the stages of its growth, and this principle has adopted many of the research, despite the difficulties faced by researchers in this door and remind that at the end of this article. The following are some of the projects antibiotics as growth stages of the virus: Need most viruses to merge their membranes with the cell membrane so that it can be accessed, nor can any virus was to enter any cell that was, but that all kind of viruses intended a particular type of cell, because he needs to find receptors on their membranes fit the items on its membrane so be able to access them, just as the key and the lock. The researchers took advantage of this intimate relationship when they found antioxidants preventing a connection to the items on the membrane of the virus on the cell Bmstqubladtha prevent the entry of any key in the lock. The virus empties its contents into the cell after the merger Gchaehma, and there are anti-viral inhibit this process and deprive the machine viral entry into the cell. Prescribed after the virus enters the cell to copy the genetic reservoir, there are two types of viruses: type available on the DNA and RNA on the last available such as HIV (AIDS). For the first type, the antibiotics are a isotopes Nichaeliosedat any Nichaeliosedat modified and which hinder the process of transcription, as previously explained, the second type setting calls to convert RNA into DNA by the enzyme transcriptase inverase before embarking on the process of transcription in this case there are two types of antibiotics: type in the form of isotopes Nichaeliosedat as explained previously and another kind in the form of particles of active intervention in the space of an enzyme transcriptase inverse transformation and so without the DNA from RNA. Require DNA of the virus to an enzyme called integrase even be able to enter the nucleus of the target cell, but so far there is no anti-viral can resist this enzyme, and still the search field and wide in this section, and despite the success of some experiments in the laboratory, the emphasis on the ground has not yet been . After the completion of the process of copying DNA virus is produced viruses sons and some species depend on the cell membrane to enclose their content, and there are some antibiotics that deprive these new viruses from the cell membrane and thereby prevent the continuity and spread. Virus proteins are immature children when some species, and enzymes you need to enable them to transition to a mature and functional proteins, but the intervention of a special anti-paralyzing these enzymes and viruses deprives children of their maturation proteins leading to eliminate them. Obstacles and problems Due to the few large anti-viral to a number of problems and obstacles, including: When the virus enters the cell, it is bound to merge with its components, and therefore antibiotics, which may mean the virus destroys the cell as well, and researchers are working on finding fights anti-virus only without damaging the cell. May get a great success for some antibiotics at the level of laboratory experiments on humans, but the application does not come desired result. Viruses evolve dramatically and therefore difficult to monitor and eliminate them, once the scientists found they had received some antibiotics resistance of viruses that change shape and genetic program for future generations to escape from them. And maligned as well as the antibiotics caused in many of the side effects, and cost-prohibitive to discover and study. While waiting for the development of this field, the remaining vaccines are the most effective means for the prevention of viruses. And preventative vaccine is a product able to guarantee immune protection against the disease, and consists of the virus itself, but not be a nurse and is unable to reproduce. The experts are working on the development of another type of vaccine, a therapeutic vaccines, which rely on the same principle of preventive vaccines, but addressed to the people infected to strengthen immunity against it. It is hoped further research focused on a protein called interferon interferon riding by cells infected with the virus to protect neighboring cells.
