The human genome moderate fragments of viruses that our metal money knot with in our distant evolutionary past . Now unexampled scientific research has isolated some of the viruses that still stalk our genomes , even after million of years of evolution . In today ’s Scientific American , Katherine Harmon has a great roundup of new study of the retrovirus genes that lurks in our own genome , as well as in the genome of other sprightliness forms .
Harmon write :
Genetic code from retroviruses has been found to compose some 8 percent of the human genome , having been copied in during replication and left to be inherited by us and our issue . But non - retroviral RNA viruses do not use their master of ceremonies ’s DNA to replicate - and some do not even enter the host cell ’s core . Nevertheless , raw research has turn up surprising grounds that some of these virus are enmeshed in the genomes of craniate - include man and other mammals .
One of these young studies , issue online July 29 in PLoS Pathogens , has uncovered some 80 examples of viral familial information circulating in the genome of vertebrate mintage for the retiring 40 million years .
To discover these association , the group work estimator analyses of 5,666 genes from all acknowledge non - retroviral , single - run aground RNA virus families against the genome of 48 craniate species . The strongest matches belonged to just two virus radical : Bornaviruses and filovirus , the latter of which include the deadly Ebola and Marburg hemorrhagic fever pathogens .
