Abstract
We have carefully examined the frequency of guanidine-resistant revertants in six different clonal pools of guanidine-dependent mutants of type 1 poliovirus. The mutation frequency was (6.5 +/- 6.3) x 10(-4) (with all amino acid substitutions occurring at position 227). The minimal corrected base substitution frequency per single nucleotide site in the codon for amino acid 227 was (2.1 +/- 1.9) x 10(-4).Entities:
