| the arrangement of information in dna molecules. | the anatomy of dna molecules isolated from mature bacteriophage is reviewed. these molecules are linear, duplex dna consisting mainly of uninterrupted polynucleotide chains. certain phage (t5 and pb) contain four specifically located interruptions. while the nucleotide sequence of most of these molecules is unique (t5, t3, t7, lambda), some are circular permutations of each other (t2, t4, p22). partial degradation of these dna molecules by exonuclease iii predisposes some of them to form circles ... | 1966 | 5967428 |

| studies on phage development. ii. the maturation of t4 phage in the presence of puromycin. | maturation of t4 can proceed in the presence of 5-methyltryptophan or puromycin. puromycin inhibits phage protein synthesis within a few seconds, thus limiting the amount of phage precursor material available for maturation. after the arrest of protein synthesis, maturation continues unabated until the limiting protein precursor is depleted. at least one protein, the tail fiber protein, is depleted. phage protein maturable in the presence of puromycin appears about 5 minutes before maturation be ... | 1966 | 18611470 |
| studies on phage development. iii. the fate of t4 dna and protein synthesized in the presence of 9-aminoacridine. | 9-aminoacridine (9aa) inhibits maturation of phage t4. upon diluting infected bacteria from the dye into a medium containing an inhibitor of protein synthesis, one obtains a crop of mature phage made out of the material accumulated before the removal of 9aa. dna is synthesized in the presence of 9aa and continues to replicate after the removal of 9aa and addition of puromycin. by marking the dna with 5-bromodeoxyuridine (budr) and studying the light sensitivity of the phage produced by cells exp ... | 1966 | 18611471 |

| cellular heterogeneity in the production of an anti-hapten antibody. | single lymph node cells from rats immunized with a conjugate of 3-iodo-4-hydroxy-5-nitrophenyl acetic acid chloride (nip) and chicken globulin were tested against either nip or nnp conjugated with bacteriophage. nnp is related to nip but has a nitro group instead of iodine. the conjugated phages were still infective but easily inactivated by anti-hapten sera at a serum concentration of 10(-7). phages carrying a related hapten were less sensitive to antibody than phages conjugated with the immuno ... | 1967 | 4165500 |

| properties of r mutants of bacteriophage t4 photodynamically induced in the presence of thiopyronin and psoralen. | about 4 x 10(-4)r mutants were induced per lethal hit, a frequency characteristic of weak mutagens. collections of mutants produced in the presence of either dye were indistinguishable in most of their properties. the rii mutants differed sharply from spontaneous mutants in their mutational spectra (fine scale map distribution) and their reversion responses to specific mutagens. few or none of the induced mutants were induced to revert with proflavine (sign mutants; reading frame shift mutants). ... | 1967 | 5623962 |
| differential effect of polyamines on t4 morphogenesis. | the 5-fluorouracil (5 fu) technique for the phenotypic reversion of amber mutants was used to demonstrate that under certain circumstances, in the presence of putrescine or spermidine, early mutants have an enhanced response to 5 fu, whereas late mutants have a delayed response. bacteria infected by t4d wild-type bacteriophage did not produce phage in the presence of high putrescine concentrations. pulse treatments with putrescine showed that the production of lysozyme depends on a putrescine-se ... | 1967 | 5623974 |
| selective gene transcription in bacteriophage t4 by putrescine. | messenger ribonucleic acid (mrna) preparations from t4-infected cells formed in the presence or absence of putrescine have been characterized and compared. hybrid competition experiments indicate that these mrna molecules are derived from distinct genetic loci. the results are consistent with the hypothesis that putrescine might control differential transcription of the phage genome during morphogenesis. the data are also in accord with previously observed changes in the population of mrna forme ... | 1967 | 5623975 |

| lysis inhibition in escherichia coli infected with bacteriophage t4. | a technique of continuous filtration of t4-infected escherichia coli has been devised to study the phenomenon of lysis inhibition. studies using this technique revealed that the length of the lysis delay caused by superinfection can attain only certain discrete values, which for low average multiplicity of superinfection is thought to be a reflection of the actual number of superinfecting particles per cell. the time interval between primary and superinfection had little effect on the length of ... | 1967 | 4912240 |
| growth of a dihydrofolate reductaseless mutant of bacteriophage t4. | a mutant of bacteriophage t4 was isolated which was unable to induce virus-specific dihydrofolate reductase in infected cells. the mutant was able to form several other early enzymes of pyrimidine metabolism. growth of the mutant in a wild-type host, escherichia coli b, was compared with that of the parent strain, t4bo(1), and t4td8, a mutant which lacks the ability to induce thymidylate synthetase. growth studies were carried out in minimal medium, which gave higher growth rates and phage yield ... | 1967 | 4912241 |
| molecular recombination in t4 bacteriophage deoxyribonucleic acid. ii. single-strand breaks and exposure of uncomplemented areas as a prerequisite for recombination. | deoxyribonucleic acid (dna) from several "dna-deficient" amber mutants was observed to be either nicked (amber 22, 82, 122, and wild type) or cut (amber 453) after injection into a nonpermissive host. this effect was inhibited by chloramphenicol (cm), indicating that it is due to phage-induced enzymes. although most of the mutants tested for replication in a density-label system were in fact dna-deficient (amber 22, 82, 122), one (amber 81) was found to replicate almost identically to the wild t ... | 1967 | 4912244 |
| control of bacteriophage-induced enzyme synthesis in cells infected with a temperature-sensitive mutant. | the timing of "early" and "late" protein synthesis in escherichia coli infected with t-even bacteriophage was studied with a temperature-sensitive phage mutant, t4 tsl13. this strain was completely unable to direct the synthesis of phage deoxyribonucleic acid (dna) at 44 c because it makes a deoxycytidylate hydroxymethylase which cannot act at that temperature. however, the mutant did multiply normally at 30 c. no detectable formation of the late protein, lysozyme, occurred at 44 c, in agreement ... | 1967 | 4918234 |

| total and free triiodothyronine in human serum. | a reliable method has been developed for the determination of total serum t3, dialyzable fraction (dft3), and absolute concentration of free t3 (aft3). total t3 values (mean +/- sd) were: healthy euthyroid subjects, 0.33 +/- 0.07 mug per 100 ml; hyperthyroid patients, 0.71 +/- 0.1 mug per 100 ml; hypothyroid, 0.10 +/- 0.03 mug per 100 ml. values (mean +/- sd) for dft3 in these groups were 0.46 +/- 0.14%, 0.78 +/- 0.17%, and 0.16 +/- 0.08%, respectively. calculated values for aft3 were: 1.51 +/- ... | 1967 | 16695923 |
| streptomycin suppression of ambivalent phage mutations. | phenotypic repair by streptomycin has been studied in amber mutants of phage t4 on su- strains, as has the interference of smr mutations with amber suppressors. the repair seems not to be specific; however a temporal specificity of streptomycin action has been demonstrated by means of pulse experiments. the dependence of the efficiency of suppression upon experimental condition is also reported. | 1967 | 18614055 |
| effect of phage on amino acid activation. | infection of escherichia coli np2 with t-even phage strains is known to cause the appearance of a new valyl trna synthetase activity. in the present work mutant hosts possessing altered activating enzymes for phenylalanine, glycine, or histidine were employed to detect possible phage-induced modifications in the translating systems for these amino acids. the results establish that t4 has an absolute requirement for the phenylalanyl trna synthetase of its host, probably in an unmodified form, and ... | 1967 | 18614089 |
