The life cycle of hyperploid S3 HeLa cells, irradiated with sublethal doses of x rays, was studied. A reversible mitotic lag was readily demonstrated at doses of 34 to 135 rads, prcduced by a block localized in the G2, pre-mitotic period. Visible chromosomal aberrations were produced in a majority of the cell population at these doses. It was proposed that this reversible mitotic lag, like irreversible reproductive death, is due to chromosomal damage and that the reversible lag may reflect interference with chromosomal condensation just prior to and perhaps in the early parts of the mitosis.
