However, in comparisons of A3A (red) and A3B (blue) APOBEC3 TCW mutation frequencies in ssDNA loop regions of hairpins and equivalent data sets from aggregate controls (blue boxes: the catalytic mutant of each protein and eGFP), the A3A data set approaches statistical significance (P = 0.0655) and the A3B data are significantly different (P = 0.0367) by Welch’s t-test.
