Abstract
Several responses of synchronized populations of HeLa S3 cells were measured after irradiation with 220 kev x-rays at selected times during the division cycle. (1) Survival (colony-forming ability) is maximal when cells are irradiated in the early post-mitotic (G(1)) and the pre-mitotic (G(2)) phases of the cycle, and minimal in the mitotic (M) and late G(1) or early DNA synthetic (S) phases. (2) Markedly different growth patterns result from irradiation in different phases: (a) Prolongation of interphase (division delay) is minimal when cells are irradiated early in G(1) and rises progressively through the remainder of the cycle. (b) Cells irradiated while in mitosis are not delayed in that division, but the succeeding division is delayed. (c) Persistence of cells as metabolizing entities does not depend on the phase of the division cycle in which they are irradiated. (3) Characteristic perturbations of the normal DNA synthetic cycle occur: (a) Cells irradiated in M suffer a small delay in the onset of S, a slight prolongation of S, and a slight depression in the rate of DNA synthesis; the major delay occurs in G(2). (b) Cells irradiated in G(1) show no delay in the onset of S, and essentially no alteration in the duration or rate of DNA synthesis; G(2) delay is minimal. (c) Cells irradiated in S suffer an appreciable S prolongation and a decreased rate of DNA synthesis; G(2) delay is shorter than S delay.

Abstract
Interferometric and photometric measurements have been made successively on individual cell nuclei derived from normal embryonic tissues and spontaneous tumour tissues of the mouse grown in vivo. From the measurements, the relations between nucleic acid and dry mass content have been studied in the two types of nuclei and the results shown to be consistent with differences in cell metabolism previously reported to exist in vitro. In the nuclei of normal embryonic cells, the syntheses of DNA, nuclear RNA, and protein appear to be closely associated, whereas in the tumour cell nuclei an appreciable fraction of the chromatin RNA and protein synthesis is dissociated from the replication of DNA.

Abstract
The replication time and pattern have been investigated in hepatoma cells induced by feeding 3'Me-DAB to male rats for 5 months. With the use of tritiated thymidine as a DNA label along with autoradiography, mitotic nuclear labeling has been studied 0.5 to 72 hours after the administration of the label. The following time intervals have been estimated: replication time, 31 hours; DNA synthesis, 17 hours; G(2) plus Mitosis, 2 hours; G(1), 12 hours. Only about 8 per cent of the tumor cell (interphase) population is "flash" labeled, following a single dose of 50 microC of H(3)TDR. This group of cells has been followed through three cycles of division. The repeated rhythmic passage of tumor cells through cell division is similar to that previously reported for normal liver cells in the growing rat. However, tumor cells have longer replication and DNA synthesis times. In addition, the several time intervals studied vary more in the tumor cell population than they do in the growing normal cell population.
