Q-mediated late gene transcription of bacteriophage lambda: RNA start point and RNase III processing sites in vivo.

abstract：:Feline foamy virus (FeFV) belongs to the group of spumaretroviruses that contain in addition to gag, pol, and env accessory genes collectively called bel genes. Primate FVs have been shown to utilize internal promoters in addition to the 5' LTR promoters. In contrast to other known retroviruses, the FV pol genes are e...
