Once the virus is inside the body human will invade different cells to keeping them in sleep mode, or active well.
When it is in sleep mode the individual will not manifest symptoms of any kind, while at the very moment that turns there Yes to transmit genes to the cell and this will be a manufacturer of new virus particles to be extended so phenomenal to other cells.
Moreover, the virus, is a microorganism tiny, invisible even to the optical microscope, which multiply in living cells and is the source of a myriad of diseases.
All types of organisms such as animals, plants, human, among others, can be achieved by viruses.
The first virus detected formally was the tobacco mosaic that infects the leaves of plants. In the year 1899, the Dutch microbiologist Martinus Willem Beijerinck discovered it, although, for some time which had been attacking the plants.
Viruses have a simple structure, are comprised of a nucleic acid molecule, either DNA or RNA, that is within a protein. It is worth to indicate that in cases of plant viruses have RNA, while animals can give the two alternatives RNA and DNA.
Its enormous danger is rooted precisely in that once he invaded the cell and reproduced, inevitably, will cause the destruction of the same. It should be noted is that the immune system of human beings, sometimes rejects these viruses and in this sense vaccines that have been created to combat some of them prove to be vitally important to give force to the mentioned system and of course to neutralize the virus.
There are different types of viruses: bacteriophages, plant pathogens, and the zoopatogenos.
