AB One aspect of the Theory of Genotypic Selection states that G:U base
pairs are selected for function and structure. RNA secondary structures
stabilised by G:U base pairs are suggested to be involved in the
evolution of attenuated strains of polio virus. Asymmetric mutations
(C-->U and A-->G) and convergent evolutionary solutions are explained as
a direct consequence of G:U base pairing. The possibility of a naturally
occurring attenuated strain of HIV-1 is predicted.
