8-oxo-dG bypass fidelity by RB69 polymerases

	L+	L−	F+	F−
Light blue plaques	87.5% (1108)	84.6% (1549)	91% (1065)	82.3% (1205)
Dark blue plaques	10% (127)	13.7% (251)	8.2% (96)	17.2% (252)
dATP:Go (%)	17	23	14	29
C:A ratio	5.0	3.4	6.3	2.5

In parentheses are the numbers of plaques scored. A small percentage of plaques were colorless due to sequence changes within the chemically synthesized oligonucleotides and/or due to occasional polymerization errors located at positions other than at the nonsense codon.
