Kinetosome Production in Condylostoma Occurs During Cell Division*
This investigation was supported by Research Grant GB-24544, from the National Science Foundation, institutional Grants CA-06927 and RR-05539, from NIH, U. S. Public Health Service, and by an appropriation from the Commonwealth of Pennsylvania.
SYNOPSIS
Kinetosome counts in different stages of the cell cycle of Condylostoma indicate that somatic kinetosome production occurs during cell division. The kineties apparently increase in length during interphase by spacing-out of preexisting kinetosomes. This spacing-out may be passive and caused by expansion of the cortical membrane to which the kinetosomes are attached.
