The aim is to understand how RNA virus mutations contribute to survival and fitness dynamics in various environments.
Explored mutation rates and effects in different environmental contexts.
Utilized in vitro hypermutation reactions to investigate functional sequences.
Analyzed the evolutionary impact of population size and bottleneck events on viral fitness.
Viruses with larger population passages showed greater fitness gains compared to those with bottlenecks.
Fitness changes often occur with environmental shifts, indicating trade-offs in mutation effects.
RNA viruses exhibit limited mutation tolerance within their evolutionary potential.

Domingo et al. (1997) studied this question.
