Fig. 6. Centriole length in
-tubulin-depleted cells. The length of interphase and mitotic centrioles was determined on longitudinal sections obtained by electron microscopy from control (A) and treated (T
23C) (B) cells. The two length distribution profiles were significantly different as checked by a homogeneity test based on variance analysis: an experimental score of 41 against a theoretical score of 7 for a security of 99% [according to Snedecor's tables (De Muth, 1999)] indicating that
-tubulin depletion reduces centriole length.
