title: Studies on changes in the nuclear helices of Amoeba proteus during the cell cycle.
abstract: The fine structure of the nuclei of synchronously growing cell population of Amoeba proteus was studied at I-h intervals during the interphase. This study showed that the nuclear helices undergo increases in their number at certain stages during interphase. These changes were found to correlate with ultrastructural changes occurring in the nucleoli.
