Abstract:
:Retroviruses, like other RNA viruses, mutate at very high rates (0.05-1 mutations per genome per replication cycle) and exist as complex genetically heterogeneous populations ('quasispecies') that are ever changing. De novo mutations are generated by inherently error-prone steps in the retroviral life cycle that introduce base substitutions, frame shifts, genetic rearrangements and hypermutations.
