Fig. 6.

(a) Percentage of base loss from A (Δm 135.05 Da), C (Δm 111.04 Da), G (Δm 151.05 Da), and U/Ψ (Δm 112.03 Da) in CAD of h_i−22 from hydrolysis of the U-sequence (circles) and Ψ-sequence (triangles), with 100% = [h_i−22 − 135.05] + [h_i−22 − 111.04] + [h_i−22 − 151.05] + [h_i−22 − 112.03]; the sequence on top is meant to indicate the nucleobase terminating a given hydrolysis product (b) differences between U- and Ψ-sequences in base loss from A (open squares), C (open triangles), G (open circles), and U/Ψ (filled triangles).
