WebHIV RT lacks the proof-reading capabilities inherent in cellular polymerases, meaning that its duplication of the HIV genome is highly error-prone. Mutations due to uncorrected RT activity appear in the HIV genome at a rate of about 1 in every 1500–4000 nucleotides per replication cycle. WebHIV is a retrovirus, which means it carries single-stranded RNA as its genetic material rather than the double-stranded DNA human cells carry. Retroviruses also have the …
