| repair of pyrimidine dimer damage induced in yeast by ultraviolet light. | crude extracts from ultraviolet (uv)-irradiated yeast cells compete with uv-irradiated transforming deoxyribonucleic acid (dna) for photoreactivating enzyme. the amount of competition is taken as a measure of the level of cyclobutyl pyrimidine dimers in the yeast dna. a calibration of the competition using uv-irradiated calf thymus dna indicates that an incident uv dose (1,500 ergs/mm(2)) yielding 1% survivors of wild-type cells produces between 2.5 x 10(4) to 5 x 10(4) dimers per cell. wild-typ ... | 1972 | 4551759 |
| new small polypeptides associated with dna-dependent rna polymerase of escherichia coli after infection with bacteriophage t4. | four new small polypeptides are associated with dna-dependent rna polymerase from e. coli after infection with t4 phage. the new polypeptides are easily detected in rna polymerase from e. coli cells labeled with amino acids after phage infection. their molecular weights range from 10,000 to 22,000, as detected by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. all four polypeptides are found after infection with either wild-type t4 phage or t4 early amber mutants in ... | 1972 | 4551978 |

| repair replication in escherichia coli as measured by the photolysis of bromodeoxyuridine. | the ability to selectively photolyze bromouracil-(brura-)containing repaired regions in cellular dna has allowed us to estimate the average size of repaired regions in ultraviolet (uv) light-irradiated escherichia coli. cells were labeled with thymidine-(3)h, irradiated at 254 nm, and incubated in nonradioactive bromodeoxyuridine (brdurd). after incubation the cells were exposed to 10(6) ergs.mm(-2) at 313 nm, lysed, and sedimented in alkaline sucrose gradients so as to measure the average molec ... | 1972 | 4553318 |
| specific endonuclease r fragments of bacteriophage phix174 deoxyribonucleic acid. | the restriction enzyme from hemophilus influenzae, endonuclease r, cleaves phix174 replicative-form deoxyribonucleic acid (dna) into at least 13 specific limit fragments. the molecular weights of 12 of the fragments have been estimated by gel electrophoresis and electron microscopy. using the genetic assay for small fragments of phix dna, we have shown that we can salvage markers from the endonuclease r phix-rf fragments. | 1972 | 4553678 |

| data processing in hospital bacteriology: experience of 18 months' trial. | the nature of bacteriological investigations creates data processing problems. non-numerical results must be coded. this may be done retrospectively or at the bench, the former method involving extra work and staff, the latter implying simple codes, stringent checking, a nearby computer, and decoding programs. the use of a shared computer for producing daily reports diminishes departmental autonomy. benefits occur in more readily available records and statistics, quality control, epidemiology, a ... | 1972 | 4555043 |

| homology between the deoxyribonucleic acids of haemophilus influenzae and haemophilus parainfluenzae. | to determine the degree of homology between deoxyribonucleic acid (dna) from haemophilus influenzae and that from haemophilus parainfluenzae, the two dnas were hybridized by the membrane-filter technique. it was found that 44% of the dna from each species was sufficiently homologous to allow hybrid formation. | 1972 | 4563974 |
| dna modification methylase activity of escherichia coli restriction endonucleases k and p. | the highly purified restriction endonucleases of e. coli k and coliphage p1 transfer methyl groups from s-adenosylmethionine to adenine residues of unmodified dna. incubation of unmodified dna with endonucleases k or p and s-adenosylmethionine renders the dna resistant to restriction. the enzymes, therefore, have both restriction endonuclease and modification methylase activities. | 1972 | 4564204 |

| effect of monosodium n-alkylsalicylates on spores of bacillus subtilis. | the effects of several monosodium n-alkylsalicylates on washed spores of bacillus subtilis have been examined. none of the compounds was sporicidal, but in general they prevented dormancy induced by incubating the spores in water. this effect was related to the position in the ring and size of the alkyl groups substituted on the salicylic acid nucleus. | 1972 | 4621799 |
