Translation Of The L-Species Dsrna Genome Of The Killer-Associated Virus-Like Particles Of Saccharomyces Cerevisiae, James E. Hopper, Keith A. Bostian, Lucy B. Rowe, Donald J. Tipper Dec 1977

Translation Of The L-Species Dsrna Genome Of The Killer-Associated Virus-Like Particles Of Saccharomyces Cerevisiae, James E. Hopper, Keith A. Bostian, Lucy B. Rowe, Donald J. Tipper

Microbiology and Physiological Systems Publications

Virus-like particles containing the L (P1)-species of double-stranded RNA (dsRNA) were isolated from Saccharomyces cerevisiae, and the translational activity of the virus-like particle-derived dsRNA was analyzed in the wheat germ cell-free system. Denaturation of the dsRNA immediately prior to in vitro translation resulted in the synthesis of one major and at least three minor polypeptides, whereas undenatured dsRNA, as expected, did not stimulate [35S]methionine incorporation into polypeptides, but actually slightly inhibited endogenous activity. The major in vitro translation product of the denatured L-dsRNA was shown to be identical with the major L-dsRNA containing virus-like particle capsid polypeptide on ...


On The Notion That Insectivory Is A Specialized Condition, Patricia W. Freeman Dec 1977

On The Notion That Insectivory Is A Specialized Condition, Patricia W. Freeman

Mammalogy Papers: University of Nebraska State Museum

Insectivory as a specialized feeding condition in mammals has not been explored as has been carnivory or herbivory. Insect-feeding, non-edentate mammals have dilambdodont teeth and modifications in the craniomandibular joint which distinguish them from other mammals such as carnivores, herbivores, and omnivores. Variation in a family of insectivorous bats, Molossidae, can be likened functionally to the kinetic-inertial and static-pressure jaw systems noted in rhipidistians, amphibians, and reptiles. Food data show that the bats with the kinetic-inertial system eat moths and ones with the static-pressure system eat beetles. Not only do these insectivorous mammals eat insects, they also are modified to ...


Genetic Transformation Among Azotobacter Species, Wayne H. Voth Dec 1977

Genetic Transformation Among Azotobacter Species, Wayne H. Voth

Dissertations and Theses

Previous methods for genetic transformation in Azotobacter vinelandii have employed poorly defined genetic markers or crude DNA extracts. An improved transformation technique has been developed for use in Azotobacter. The technique was used to transform several strains of Azotobacter with DNA carrying a defined genetic marker. A method for isolating pure, high molecular weight, biologically active DNA from Azotobacter is also presented. Purity of the extracted DNA was determined by standard chemical assays. The molecular weight was determined by boundary sedimentation techniques to be 18.2 megadaltons. DNA was obtained from several mutant strains of Azotobacter. Biological activity of these ...

The Effects Of Dimethyl Sulfoxide (Dmso) On The Synthesis Of Lens Protein In The Developing Rat, Annie Ruth Rice Dec 1977

The Effects Of Dimethyl Sulfoxide (Dmso) On The Synthesis Of Lens Protein In The Developing Rat, Annie Ruth Rice

ETD Collection for AUC Robert W. Woodruff Library

The lens crystallins have been utilized by a variety of investigators who are interested in the biochemical differentiation of the vertebrate lens, Dimethyl Sulfoxide (DMSO) is known to be very effective in altering the configuration of proteins. Synthesis of the crystallins may be altered by the use of DMSO. It was the purpose of this investigation to determine if alterations do occur and if so in what manner do these alterations affect the developing eye of rat fetuses of the Long-Evans strain. Lenses from fetuses of normal and DMSO-treated maternal rats showed marked changes in protein concentration and moieties. The ...

Sixty-Five Years Of Whooping Crane Records In Nebraska, Paul A. Johnsgard, Richard Redfield Dec 1977

Sixty-Five Years Of Whooping Crane Records In Nebraska, Paul A. Johnsgard, Richard Redfield

Nebraska Bird Review

In 1933, Myron Swenk determined the status of the Whooping Crane in Nebraska by summarizing all of the records then available to him, and established the general pattern of timing and geographic distribution of Whooping Crane occurrence in this state. Although the population of this species has remained very low since that time, a sufficient number of observations have been made to warrant updating his analysis and comparing the more recent records with these earlier ones. During the summer of 1977 the junior author undertook such a summary as a class project, by extracting such records from all of the ...


Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe Dec 1977

Aspects Of Reproduction And Population Dynamics Of Bobcats In Wyoming, Douglas M. Crowe

Great Plains Wildlife Damage Control Workshop Proceedings

Distribution of the bobcat includes the 48 contiguous United States and limited occupance of southern Canada and northern Mexico. There are 11 subspecies, the one in Wyoming being Lynx rufus pallescens. Bobcats inhabit an amazing variety of habitat types, from northern boreal forests, southern swamp, and cane regions to the below sea level desert of Death Valley, California. Throughout this vast area, they utilize a wide variety of prey species. One study in Wyoming revealed at least 18 different species in the stomachs of bobcats; the cottontail rabbit being predominant. A similar study in New England revealed 20 different species ...

Influence Of Endomycorrhizae On Growth Of Sweetgum Seedlings From Eight Mother Trees, Richard C. Schultz, Paul P. Kormanik, William C. Bryan Dec 1977

Influence Of Endomycorrhizae On Growth Of Sweetgum Seedlings From Eight Mother Trees, Richard C. Schultz, Paul P. Kormanik, William C. Bryan

Richard C. Schultz

Sweetgum seedlings from eight mother trees were grown in fumigated soil with or without the endomycorrhizal fungus Glomus mosseae at four levels of soil fertility for one growing season in nursery microplots. Nonmycorrhizal seedlings of all families died or failed to exceed 5 cm in height regardless of soil fertility. Endomycorrhizal seedlings suffered little mortality, averaged about 36 cm in height, and fertility level did not significantly influence their biomass. These results demonstrate that to increase the percentage of plantable seedlings in nurseries sweetgum seedlings must be endomycorrhizal. The data further suggests that adequate endomycorrhizal inoculum in nursery beds can ...

A Study Of The Water Retention Of Latex Bound Pigmented Coating Colors, Patrick T. Gibney Dec 1977

A Study Of The Water Retention Of Latex Bound Pigmented Coating Colors, Patrick T. Gibney

Paper Engineering Senior Theses

The purpose of this study was to examine the effects of three types of commercially used hydrocolloid; CMC 7M, CMC 7L, HEC 250M and KELGIN MV on water retention and on coated paper properties. It was found that the concentration of hydrocolloid was an important factor in water retention values. Carboxyl groups were theorized to be another factor in water retention. Hydrocolloids were found to lower opacity, brightness and gloss over the blank coating. Increasing hydrocolloid levels decreased the openness of the coating. When increasing the amount of hydrocolloid the IGT pick decreased. KELGIN MV gave the highest water retention ...

The Development And Assay Of An S-Phase Synchronized Cell System Using Skin Fibroblast Cultures Of The Indian Muntjac, Robert A. Cascino Dec 1977

The Development And Assay Of An S-Phase Synchronized Cell System Using Skin Fibroblast Cultures Of The Indian Muntjac, Robert A. Cascino

Biology Master’s Theses

An in vitro mammalian cell system which enables direct observation of DNA replication forks is essential to the study and understanding of the mammalian cell cycle S-phase. The prerequisite work of establishing S-phase synchronized cell cultures and an assessment of synchrony levels attained is the object of this study. Skin fibroblasts of the male Indian muntjac line which possesses large chromosomes and a low diploid number were selected for this work.

Initial block-release experiments using mitosis as an assay point indicated that 1.5 mM hydroxyurea provided marked levels of synchrony in the absence of detectable cytotoxicity. Premature chromosome condensation ...
