The SARS-CoV-2 virus and the illness it causes, COVID-19, have made an indelible mark on our lives. It seems that is also true in more ways than one; new research has shown that when the virus infects ...

A large array of viral sequences is being uncovered in eukaryotic genome sequences, revealing that almost any type of virus — not just retroviruses — can become part of host genomes. These ...

There is viral DNA in the human genome, and each instance traces back to an ancestor who was infected with a retrovirus. HIV might be the most well-known retrovirus, a microbe that can integrate its ...

The new viral particles are made by transcription of the viral genome, as with any cellular genes. If the cell divides, the viral DNA is copied and inherited, along with cellular human genes.

Although it is known that the viral genome significantly affects the spatial structure of the host genome upon entry, resulting in its integration into the host genome, the precise positional ...

Endogenous retroviruses are ancient pieces of viral DNA embedded throughout mammalian genome. Thought to be relatively inert, they are not infectious, because they lack the full complement of viral ...

Like modern HIV, these ancient retroviruses had to insert their genetic material into their host’s genome to replicate. Usually this kind of viral genetic material isn’t passed down from ...

Published in Science, a new study has shown how DNA from viruses embedded into the human genome from ancient infections can help guard our cells against some present-day viruses.. Remnants of ancient ...

Viruses are entirely dependent on their hosts to reproduce. They ransack living cells for parts and energy and hijack the ...

Small fragments of DNA from ancient viruses – called endogenous retroviruses – can be found in the genomes of many animals, from mice and chickens to cats and sheep. Retroviruses insert their RNA into ...

Bits of viral genes incorporated into human DNA have been linked to cancer, ALS and schizophrenia. But many of these genes may not be harmful, and could even protect against infectious disease.
