The re-transcribed DNA is then integrated into the genome of the host cell (Figure 2). This process requires the absence of the nuclear membrane and thus is restricted to the M-phase of proliferating ...

Retroviruses are a sub-category of oncoviruses that include the lentiviruses. Retroviruses are negative single-stranded RNA viruses in which tRNA serves as a primer for the mRNA synthesis. The mRNA is ...

ARLINGTON, Va.-Studies on common baker's yeast have led to the discovery of what may be a long-sought mechanism in the life cycle of retroviruses, including the human immunodeficiency virus (HIV).

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

Retroviruses are a family of viruses that use RNA instead of DNA as their genetic material. The 'retro' designation comes from the fact that retroviruses copy their RNA back into DNA once they get ...

Ancient viral fossils buried in our DNA are offering fresh clues about how today’s respiratory pathogens infect and spread. By tracing the shared architecture between long-extinct retroviruses and ...

Ancient viruses have really gotten on our nerves, but in the best of ways. One particular retrovirus — embedded in the DNA of jawed vertebrates — helps turn on production of a protein needed to ...
