WebHIV Long Terminal Repeat. Regulatory sequences important for viral replication that are located on each end of the HIV genome. The LTR includes the HIV ENHANCER, promoter, … A long terminal repeat (LTR) ... usually terminating by the addition of a poly A tract just after the R sequence in the 3' LTR. The finding that both HIV LTRs can function as transcriptional promoters is not surprising since both elements are apparently identical in nucleotide sequence. Instead, the 3' LTR acts in … See more A long terminal repeat (LTR) is a pair of identical sequences of DNA, several hundred base pairs long, which occur in eukaryotic genomes on either end of a series of genes or pseudogenes that form a retrotransposon or … See more The LTR-flanked sequences are partially transcribed into an RNA intermediate, followed by reverse transcription into complementary DNA (cDNA) and ultimately dsDNA (double-stranded DNA) with full LTRs. The LTRs then mediate integration of the DNA via an … See more • Direct repeat • RetrOryza • LTR retrotransposon See more As 5' and 3' LTRs are identical upon insertion, the difference between paired LTRs can be used to estimate the age of ancient retroviral insertions.
