Fig. 1From: Distribution and fate of HIV-1 unintegrated DNA species: a comprehensive updateFates of viral cDNAs (reverse transcripts) after reverse transcription. After reverse transcription, HIV-1 produces cDNAs that may either be integrated into host genome or circulate themselves. Otherwise, they are degraded into free nucleotides. Circular DNAs have been reported to actively participate in current gene expression similar to the integrated DNAs followed by linearization, degradation, or accumulation as a reservoirBack to article page
