Abstract
DNA replication in isolated nuclei from synchronized HeLa cells has been studied in an effort to optimalize the system and characterize the product. The synthesis was highly dependent on the four deoxyribonucleoside triphosphates, ATP, and Mg2+. Optimum pH was about 7.8. The system was further stimulated by monovalent ions with NH4Cl and Tris-HCl (each 65 mM) being the most effective. The four ribonucleoside triphosphates and glycerol gave a slight but very reproducible and additive stimulation. Low concentrations of spermine and spermidine (0.2-1.5 X 10(-4) M) were also slightly stimulatory (10-15%) whereas higher concentrations were inhibitory. The reaction product was DNase sensitive, and banded at 1.699 g/ml in neutral CsCl together with bulk HeLa nuclear DNA. When studied by neutral CsCl and alkaline Cs2SO4 gradients, the incorporation of [3H]TTP was mainly (more than 85%) due to further elongation of strands initiated in vivo as evidenced by BrdUrd labeling.

Abstract
Nuclei were isolated from synchronized HeLa cells in the S-phase by a modification of the non-aqueous method described by Kirsch et al. (Science (1970) 168, 1592-1595). The method involved lyophilization of the cells, homogenization in non-aqueous glycerol and centrifugation in a gradient of 0-35% (w/w) 3-chloro-1,2-propanediol in glycerol. Such nucleic incorporated deoxyribonucleotides into DNA when incubated in an aqueous buffer containing Mg2+, ATP, dATP, dGTP, dCTP and dTTP. The product was sensitive to DNAase and banded with bulk DNA in isopycnic centrifugation. Sedimentation of the product in alkaline sucrose gradients after labelling of the nuclei for 2 min revealed labelled material in the 5 S peak and in the 18 S area. The material in the 5 S peak moved into the 12 S area after a 13 min chase.

Abstract
Examination of labeling patterns of proteins in Chinese hamster cells(line CHO) revealed the presence of a class of protein(s) that is synthesized during G1 phase of the cell cycle. Cells arrested in G1 by isoleucine (Ile) deprivation were prelabeded with [14-C]Ile, induced to traverse G1 by addition of unlabeled Ile, and labeled with [3-H]Ile at hourly intervals. Cells were fractionated into neclear and cytoplasmic portions, and proteins were separated by sodium dodecyl sulfate-polyacrylamide get electrophoresis. Gel profiles of proteins in the 45,000-160,000 mol wt range from the cytoplasm of cells in G1 were similar to those from cells arrested in G1 except for the presence of a mojor peak of [1-H]Ile incorporated into a protein(s) of approximately 80,000 mol wt. Peaks of net [3-H]Ile incorporation were not detected in neclear preparations. Cellular fractionation by differential centrifugation showed the peak I protein was located in the soluble supernatant fraction of the cytoplasm. Time-course studies showed that synthesis of this protein began 1-2 h after initiation of G1 traverse; the protein reached maximum levels in 4-6 h and was reduced to undetectable levels by 9 h. A cytoplasmic protein with similar electrophoretic mobility was found in G1 phase of cells synchronized by mitotic selection. This class of proteins is synthesized by cells before entry into S phase and may be involved in initiation of DNA synthesis.

Abstract
Isolated nuclei from HeLa cells can incorporate labeled ADP-ribose from NAD into an acid-precipitable product, poly(ADP-ribose). This reaction is stimulated by 4-6-fold by the addition of deoxyribonuclease I to the complete reaction mixture. If the nuclei are treated first with deoxyribonuclease I, no effect is seen; the stimulation is only apparent when the two enzymes deoxyribonuclease I and poly(ADP-ribose) polymerase, are operating at the same time. After making several minor modifications in the assay mixture, it was found that another endonuclease, micrococcal nuclease, can also stimulate the poly(ADP-ribose) polymerase activity of HeLa nuclei. A comparison of the two stimulatory effects indicated that the two endonucleases activated to the poly(ADP-ribose) polymerase activity of HeLa nuclei in the same way. Overall this evidence suggests that poly(ADP-ribose) polymerase may have a functional role in the process of DNA repair.

Abstract
Nuclei isolated from nondividing cells were induced to synthesize DNA by incubation with cytoplasm from early embryos of Xenopus laevis. Numerous replication eyes were formed in the nuclear DNA molecules, and high levels of [3-H]dTTP were incorporated. With this assay a protein(s) which appears to initiate DNA synthesis was found at high levels in the cytoplasm of eggs, blastulae, or gastrulae, but only at low levels in the cytoplasm of oocytes, hatched embryos, or adult tissues.

Abstract
Treatment of HeLa cells with a hypotonic buffer solution makes them permeable to nucleotides. Cells which are in S-phase at the time of treatment continue to synthesize DNA when supplied with the four deoxyriboside triphosphates, ATP, Mg2+, and the proper ionic environment. DNA replication extends from sites which were active in the cells prior to treatment. The product is confined to the nucleus and is sensitive to deoxyribonuclease. Under optimum conditions, up to 5% of the HeLa genome can be replicated from exogenous nucleotides. In synchronized cultures the level of DNA replicase activity, as measured in permeable cells at different points in the cell cycle, correlates with the rate of [14C] thymidine incorporation measured in the living, untreated cells.

Abstract
DNA replication was studied in nuclei isolated from phytohemagglutin-stimulated bovine lymphocytes. The mitogen treatment induced more than 60% of these cells to engage in DNA synthesis with a peak of synthetic activity occurring about 48 h after the addition of phytohemagglutinin. Throughout this response the ability of isolated nuclei and nuclear sonicates to synthesize DNA in vitro was proportional to the synthetic ability of the intact cells of origin. The subcellular systems appear to continue synthesis at replicative sites which were active in vivo. The rate of in vitro synthesis by both nuclei and nuclear sonicates was about two-thirds that of intact cells. The one cytoplasmic and two nuclear DNA polymerase activities separated from these cells were found to have properties similar to those of other eucaryotic cells.

Abstract
The biosynthesis of alpha factor, a mating-type-specific regulatory oligopeptide which is secreted by Saccharomyces cerevisiae cells of alpha mating type, was studied. In batch cultures only small amounts of the peptide were synthesized during the exponential growth phase. During the stationary phase, alpha factor was produced at a constant rate and accumulated in the culture medium. Inhibition of translation in wild-type cells by cycloheximide, or in mutant strains under conditions which blocked protein or ribonucleic acid (RNA) synthesis completely inhibited the production of alpha factor. These results indicate that the factor is produced by ribosomal translation of a specific messenger RNA and not by an extraribosomal mechanism of peptide synthesis.

Abstract
Nuclei isolated from African green monkey kidney cells infected with simian virus 40 at different times after infection maintain in vitro the same temporal sequence of host and viral DNA synthesis as that seen in intact cells. The viral DNA synthesized by the nuclei of cells previously infected for 32-35 hr was characterized by centrifugation through neutral and alkaline sucrose gradients, and by isopycnic banding in a propidium iodide-cesium chloride gradient. DNA synthesis in this system is maintained for only 4-5 min. Neutral sucrose gradient analysis showed that most of the radioactivity is associated with the replicative intermediate of simian virus 40 DNA and the rest sediments at 5-7 S. Alkaline gradient analysis showed that 50-60% of the radioactivity sediments as 3-7S fragments, and the rest between 7 and 16 S. Pulsechase experiments showed that in this system 3-7S fragments do not mature into long chains. A model is presented to explain the failure of these fragments to join into long chains in this in vitro nuclear system.

Abstract
A lysate from hypotonically swollen polyoma-infected BALB/3T3 cells incorporated labeled deoxynucleotide triphosphates into both viral and cellular DNAs. The incorporation was stimulated by the presence of ATP, deoxynucleotide triphosphates, thiols, and magnesium ions. Strong inhibition of incorporation was observed with thiol reagents and arabinosyl nucleotide triphosphates. The rate of in vitro synthesis increased with the temperature of incubation as expected. Incorporation into cellular DNA for up to 2 h was observed in lysates from virus-infected and serum-stimulated cells but not from resting cells. Synthesis in the system, therefore, appeared to reflect the physiological state of the cells before preparation of the lysate. Incorporation into viral DNA stopped far sooner than that into cellular DNA. During the initial phase of the in vitro incubation, incorporation occurred into viral replicative intermediates (RI). These RIs had identical properties to those isolated after in vivo pulse labeling and a substantial proportion of them was matured to form I DNA at later times in the incubation through all the stages known to occur in vivo. Density labeling of the in vitro product showed that practically all of the RIs pre-existing in the infected cell took part in the in vitro reaction. Analysis of DNA labeled in vitro in the presence of 5-bromodeoxyuridine triphosphate showed that synthesis occurred on RIs at all stages of replication and that the progeny strands were elongated by up to 80% of unit viral DNA length. Pre-existing RIs, pulse labeled in vivo, showed evidence of a pool at a late stage of replication which required elongation of their progeny strands by approximately 25% during conversion to form I molecules. From density-labeling experiments, we were also able to show that viral DNA synthesis in vitro was semiconservative. The major reason for cessation of viral DNA synthesis in vitro was the very limited ability of the lysate to initiate new rounds of viral DNA synthesis.

Abstract
1. The DNA polymerase (EC 2.7.7.7) activity in purified intact brain nuclei from infant rats was investigated. The effects of pH, Mg(2+), glycerol, sonication and storage of the nuclei under different conditions were examined and a suitable assay system was established. 2. The nuclei from infant brain cells were fractionated by zonal centrifugation in a discontinuous sucrose gradient into five zones: zone (I) contained neuronal nuclei (59%) and astrocytic nuclei (41%); zone (II) contained astrocytic nuclei (81%) and neuronal nuclei (19%); zone (III) contained astrocytic nuclei (82%) and oligodendrocytic nuclei (18%); zone (IV) contained oligodendrocytic nuclei (92%) and zone (V) contained oligodendrocytic nuclei (100%). 3. The content of DNA, RNA and protein for each fraction was measured. 4. The distribution of DNA polymerase activity in the fractionated infant and adult rat brain nuclei was determined. The highest activity was found in the neuronal nuclei from zone (I) and the following zones exhibited a progressive decline. In contrast with the nuclei from infant rats those from adults had a much higher activity and expressed a preference for native DNA as template. 5. The deoxyribonuclease activity in all classes of nuclei was measured with [(3)H]DNA as substrate. A general correspondence in the pattern of the relative activities in the nuclear fractions with the distribution of DNA polymerase was found. 6. The incorporation of [(3)H]thymidine into nuclear DNA in infant and adult rat brain was investigated. The specific radioactivity of the DNA in the 10-day-old rats was highest in zone (V) whereas in the nuclei of adult rats, which exhibited a comparatively low incorporation, the highest specific radioactivity was associated with zones (I) and (V).
