H If the flagellar border splits, the membrane doubtless divides also; but where the flagellum is a new formation the membrane will be too.
The small Trypanosomes resulting from either of these modes of division differ from typical adults by their stumpy, pyriform shape, the position of the kinetonucleus near the flagellar end of the body, and the absence, during the first part of their youth, of an undulating-membrane.
E - H shows the formation of the myonemes and the flagellar border (flagellum) of the undulating membrane, by means of a greatly elongated nuclear-spindle.
Further analysis of the microarray data has suggested roles for these regulatory elements other than in the control of flagellar biosynthesis.
Many of the novel predicted genes are associated with surface polysaccharide, flagellar biosynthesis and modification in addition to hypothetical genes.
