Real-time PCR analysis of HIV-1 replication post-entry events

The reverse transcriptase enzyme plays an essential role in the HIV-1 life cycle by converting a single-stranded viral RNA genome into a double-stranded viral DNA through a complex process known as reverse transcription. The resulting double-stranded DNA is integrated into the host chromosome to form a provirus. A small proportion of the viral DNAs form dead-end circular products, which nevertheless can serve as useful surrogate markers for monitoring viral replication. Utilizing real-time PCR technology, it is possible to track and quantify different stages of the reverse transcription process, the proviruses, and the nonintegrated dead-end reverse transcription products.
