RNA polymerases are sloppy. A retrovirus with an RNA genome, which is copied into DNA by a reverse transcriptase, is prone to mutations because the enzyme lacks the 3’ to 5’ proofreading capability of ...

Sequence variations in human immunodeficiency virus (HIV)-1 reverse transcriptase (RT) and protease, the molecular targets of anti-retroviral drug therapy, are prime examples of genes in which ...
It is an ester-derived prodrug that is converted in vivo by serum and tissue esterases to tenofovir, an acyclic nucleoside phosphonate (nucleotide) that inhibits HIV reverse transcriptase.
