Geneticists have recreated an ancient virus

The virus disappeared for about five million years ago, geneticists recreated under the direction of Thierry Haydmana. This research group used 30 fragments of human hereditary material, which are included in our gene copies of viral genetic information.

In ancient times, this virus was distinct infectious agents and infected cells are the ancestors of man. According to geneticists, up eight percent of human genes are those of endogenous retroviruses, that is not derived from ancestors of Homo sapiens, and joined in the genome during infection.

Much of this genetic information is inactivated in the course of mutation and is not functioning. Since the same types of viruses can multiply to penetrate into human heredity, the original genetic sequence of some species may try to install to correct accumulated errors in comparing different copies mutated randomly, and hence a different way.

The reconstruction of the virus group Haydmana made his hereditary material of a number of intentional violations, that, as scientists say, should prevent the possibility of a new spread of this microbe. Viruses returned to the existence of the species can reproduce itself only once. According to preliminary estimates, the risk of the virus for our ancestors was negligible. Furthermore, if this once lost a fight for survival, there is reason to believe that the environment of our time remains the same for him lethal, reports MIGnews. ua.
