Fig. 1From: Analysis of large deletion mutations induced by abasic site analog in human cellsThe supF mutant frequency in U2OS cells transfected with plasmid DNA containing THF (a) at position 122 of the supF gene and (b) outside of the gene (at “position 171”). Transfection experiments were performed four times. Data are expressed as the means + standard errors. *P < 0.05 vs. control plasmid (Student’s t-test)Back to article page
