Fig. 5. Profiles of sliding disintegration between two doublet bundles in elastase-treated quiescent flagella with (A-D) or without (E) severing at the basal P-bend. The distance of sliding of the thinner bundle towards the base was plotted against time. B and D correspond to Fig. 2A, right and left, respectively. (F) Relative frequencies of time lag at the onset of sliding with or without imposed bending in the axonemal fragments (upper three boxes) and the quiescent flagella with or without severing at the basal P-bend (lower four boxes).
