Structural probing of the HIV-1 polypurine tract RNA:DNA hybrid using classic nucleic acid ligands.

abstract：:In HIV-1 infection, Tat acts at least in part to control transcriptional elongation by overcoming premature transcriptional termination. In some other genes this process is governed by DNA elements called attenuators in concert with cellular transcription factors. To understand the action of Tat more fully and explore...
