Abstract excerpt

Two features of viral quasispecies are reviewed: the presence of memory genomes as minority components of their mutant spectra, and viral extinction due to enhanced mutagenesis. Memory has been documented with several genetic markers of the important animal picornavirus foot-and-mouth disease virus (FMDV). The presence of memory genomes in viral quasispecies may accelerate their adaptive response whenever a...
