Extent of DNA homology in some distantly and intimately related fishes

Creator:: Gharrett, Anthony John
Abstract:: An attempt was made to differentiate between runs of steelhead by comparing the reassociations of their DNA. Conditions for the reassociation were studied using E. coli DNA, and observations were made spectrophotometrically. Of the five buffers examined, 1.0 molar sodium perchlorate plus one-hundredth molar tris-HCl, pH 7.1, at 60° or...

Linking a growth model with logging production costing

Creator:: Bergan, Ernest E.
Abstract:: A model (called MERLIN) is presented that can allow the resource manager to consider the combined effects of silvicultural treatments and their effect on expected logging production and costs. This integrated analysis takes place within the framework of personal computer software readily available to most managers. This integration is accomplished...

Hydroperoxide formation in the radiolysis of aqueous DNA and the pyrimidine bases

Creator:: Schwiebert, Maris Carol
Abstract:: The formation of cytosine hydroperoxide was detected in aqueous cytosine solutions irradiated with Co-60 γ-rays at pH 2. The nucleotide of cytosine, cytidylic acid, forms a hydroperoxide which was detected in neutral solution. The stability of the hydroperoxides of cytosine, thymine, and their nucleotides was found to be a function...

Purification and characterization of a DNA polymerase gamma from human trophoblast tissue

Creator:: Wong, Scott W.
Abstract:: DNA polymerase gamma has been purified over 67,500-fold from human trophoblast tissue. Purification was achieved through successive chromatographies on phosphocellulose, DEAE-cellulose, DNA-cellulose, and high pressure gel exclusion through Fractogel TSK HW55. This preparation yielded a specific activity of 81 units/mg of protein using the preferred template-primer, poly (A)-oligo (dT)₁₂₋₁₃. Analysis...

Materials associated with the DNA fraction of Bacillus subtilis W168

Creator:: Laudermilk, Patricia Joan
Abstract:: The purpose of this research was to determine if a basic protein was associated with the DNA of Bacillus subtilis W168, and to determine if there was a difference in the amount and type of protein associated with the DNA at different times during the growth cycle of the organism....

Biosynthesis of streptomyces griseus phage deoxyribonucleic acid

Creator:: Shearer, Judith Ann
Abstract:: The presented study was undertaken to determine the operational catabolic carbohydrate pathway(s) contributing to the synthesis of the DNA of the actinophage for Streptomyces griseus. The incorporation of glucose-6-¹⁴C versus glucose-1-¹⁴C was determined for the deoxyribose and purine and pyrimidine bases of the phage DNA. The specific activities of the...

Cytophotometric determinations of nuclear DNA content in tissues of the wax moth larva, Galleria mellonella Linnaeus

Creator:: Longo, Frank J., 1939-
Abstract:: The present study was undertaken to determine, by measurement of nuclear DNA, the degrees and frequencies of ploidy in the last larval instar of the moth Galleria mellonella Linnaeus. While such data have been amassed for a wide variety of vertebrate tissues, few studies have been concerned with invertebrates and...

The effects of pH on the torsional flexibility of DNA bound to a nucleosome core particle

Creator:: Winzeler, Elizabeth A.
Abstract:: The effects of pH on the torsional flexibility of DNA bound to a nucleosome core particle were investigated by studying the time-resolved fluorescence anisotropy decays of ethidium bromide intercalated into the DNA of the core particle. As the torsional flexibility of DNA is affected by the presence of an intercalating...

An assay for screening cells for mismatch repair proficiency in vivo

Creator:: Wu, Shiau-Yin
Abstract:: Mismatch repair is one of the mechanisms by which cells ensure genomic stability. Deficiencies in mismatch repair (MMR) increase mutation rates and cancer risks. In the well-characterized methyl-directed Escherichia co/i system, MMR is initiated by MutS, Mut L, and MutH proteins. The single MutS protein and the single MutL protein...
