WebJun 3, 2003 · Therefore, polypurine tracts of retroviruses are essential for viral replication by reverse transcriptase (RT). These purine tracts are resistant to cleavage during first strand synthesis. In obtaining the primer for second strand synthesis, the RNase H function of RT must cleave the PPT exactly for in vivo transcription to proceed efficiently and proper … WebIdentification of a sequence element immediately upstream of the polypurine tract that is essential for replication of simian immunodeficiency virus
