Initiation of HIV-2 reverse transcription: a secondary structure model of the RNA-tRNA(Lys3) duplex.

abstract：:Four phage clones which hybridize with U1 small nuclear RNA were obtained from a rat gene library. Two clones contain a presumed pseudogene. A third clone includes two gene candidates that are co-linear with the rat U1-RNA, 3.6kb apart and in the opposite orientation. The two genes are surrounded by identical sequence...
