How did viruses evolve? Are they a streamlined form of something that existed long ago, or an ultimate culmination of smaller genetic elements joined together?

The envelope regions were shuffled to generate a recombinant library of 5 × 10 6 replication-competent retroviruses. This library was subjected to the concentration process three consecutive ...

Our services for retroviruses include production of viral supernatant by transient transfection as well as assay for replication competent retrovirus. Retroviral vector-mediated gene transfer has been ...

Proteomic characterization of murine retroviruses includes Gag protein–protein interactions, virion composition and differentially expressed cardiac proteins in the presence and absence of ethanol.

The complex retroviruses, such as HIV, encode additional trans-regulating factors or contain cis-regulating elements, thereby influencing the type and amount of transcribed RNA. The whole viral ...

"For instance, it has an unusual replication cycle and the ORF2p protein ... Because there is a kinship between ...
