| 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 |

| molecular recombination in t4 bacteriophage deoxyribonucleic acid. i. tertiary structure of early replicative and recombining deoxyribonucleic acid. | a replicative hybrid resulting from the infection of heavy (substituted with 5-bromodeoxyuridine) bacteria with light (not substituted with 5-bromodeoxyuridine) radioactive bacteriophage was isolated from a cscl density gradient. sedimentation studies indicate that 60% of the deoxyribonucleic acid (dna) behaves as if it were in units more than four times as large as an intact reference molecule. under the electron microscope, hybrid molecules appeared tangled, showed puffs and loops, occupied a ... | 1967 | 5621474 |

| 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 |

| 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 |
