abstract：BACKGROUND:All human immunodeficiency virus (HIV-1) uses a host tRNALys,3 as the primer for reverse transcription. The tRNALys,3 is bound to a region on the HIV-1 genome, the primer-binding site (PBS), that is complementary to the 18 terminal nucleotides of tRNALys,3. How HIV-1 selects the tRNA from the intracellular m...
