of three variable flagella-number mutants examined , one , vfl-2 , is dramatically defective with respect to the nbbc in that 1 ) the union between basal bodies and nucleus is very labile , 2 ) there is no detectible centrin in the nbbc region , and 3 ) total cellular centrin levels are reduced 75-80 % relative to wild type .
