aValues given are the numbers of plaques of each type counted and the resulting mutation frequencies for G/8-oxoG bypass reactions. Data shown is from experiments using a 70-mer template with streptavidin-blocked ends (see ‘Materials and Methods’ section).
bThis data has been previously published (50).
cAdditional experiments using a 45-mer template (see ‘Materials and Methods’ section) gave dark blue plaque frequencies of 32% (3′-CCGoATC), 29% (3′-CCAGoTC) and 32% (3′-CCGoAT T).
