Polypurine tract
WebHIV-1 polypurine tract. Molecular model of the polypurine tract (PPT, red) from human immunodeficiency virus-1 (HIV-1) complexed with reverse transcriptase (green). PPT is used to prime positive strand DNA (deoxyribonucleic acid) synthesis during replication of HIVs genome within the host cell.
