Blake C. Ballif, Microbiology Introduction During the past decade, the development of ancient DNA research has left modern science seemingly on the verge of breaching the barrier between the world we live in and the ancient past. Archaeologists, anthropologists, and molecular biologists alike have become increasingly more aware of the understanding that can be gleaned […]

Selenium Supplementation does not affect the Activity of the Enzyme 8-oxoguanine DNA Glycosylase
Benjamin J. Wycherly and Dr. Merrill Christensen, Food Science and Nutrition Highly reactive oxygen species produce DNA lesions, which are postulated to cause cancer. A particularly common lesion is that of an oxidized guanine residue, 8-hydroxyguanine (8-OHdG). This base is of particular concern because it can mispair with adenine during replication causing a mutation from […]
The Separation of Suspected Subspecies of Cutthroat Trout Using Mitochondrial DNA Sequences
Becky A. Shiozawa and Professor R. Paul Evans, Zoology Current mitochondrial DNA techniques using restriction fragment length polymorphisms (RFLPs) are still unsuccessful in determining phylogenetic relationships between subspecies of cutthroat trout (Oncorhynchus clarki), such as the relationships between Snake River finespot cutthroat trout and Yellowstone cutthroat trout, Bear River Bonneville cutthroat trout and Yellowstone cutthroat […]
Epigallocatechin Gallate, a Green Tea Polyphenol, causes Direct DNA Damage at Physiological Concentrations
Jeremy McBride and Dr. Kim L. O’Neill, Microbiology Epigallocatechin gallate (EGCG) is a polyphenol found in green tea. Because tea is ingested by over two thirds of the world’s population, considerable research has been done to identify and characterize the active components of the second most widely consumed beverage (1). Among the many chemopreventative properties […]
Identification of the Activator Proteins for the DNA-Protein Interaction of a Primary Cartilage Enhancer
L. Daniel Holsinger and Dr. Laura Bridgewater, Zoology Abstract: The Human col11 2 gene is responsible for the production of type XI collagen, one of the three components of the collagen triple helix. Disruption of this gene results in varied problems including dwarfism, osteoarthritis and possibly cleft palate. In order to understand more about this […]
Antigenotoxic Effects of Diallyl Disulfide and Allyl Disulfide on Benzo (a) pyrene induced DNA Damage in HepG2 Cells as measured by the Single Cell Gel Electrophoresis Assay
Corey W Speers and Dr. Kim L O’Neill, Microbiology Abstract One of the most effective strategies in cancer control is chemoprevention. Previous studies have shown naturally occurring organosulfur compounds from garlic and onion to be effective against carcinogenesis. The effects of two of these organosulfur compounds, diallyl sulfide (DAS) and diallyl disulfide (DADS), are thought […]
Sub Cellular Localization of a Putative Single Stranded DNA Binding Protein from Arabidopsis thaliana
Andrew C Edmondson and Dr. Brent L Nielsen, Microbiology and Molecular Biology DNA recombination is the exchange of segments between homologous pieces of DNA, resulting in variations in genetic diversity. Recombination provides essential genetic variation, but can also cause harmful rearrangements, resulting in genetic disorders in mammals, plants and yeast. DNA recombination in plant mitochondria […]
FDC as an HIV Reservoir: DNA Sequence Analysis of HIV Isolated from FDC and CD4+ T Cells of Infected Patient
Trever Bradley Burgon and Dr. Gregory F Burton, Microbiology Human Immunodeficiency Virus (HIV), the retrovirus that causes Acquired Immunodeficiency Syndrome (AIDS), has infected over 60 million people and become what the Joint United Nations Program on HIV/AIDS calls: “the most devastating disease mankind has ever faced” (8). Current treatment, known as HAART (highly active antiretroviral […]
Physical Mapping of DNA Sequences of Chenopod Chromosomes using Florescence in Situ Hybridization (FISH).
Theron J Baker and Dr. Eric N Jellen, Plant and Animal Sciences Quinoa (Chenopodium quinoa) is an Andean cereal chenopod known for its ideal nutritional characteristics along with its abilities to grow in drought conditions and in soils with high salt content (Fairbanks 2002). Until recently, quinoa has received little attention from the scientific community; […]
Internal Transcribed Spacer Regions of Nuclear Ribosomal DNA as a Tool For Phylogenetic Reconstruction
Melissa E. Hardy and Dr. Keith Crandall, Zoology Phylogenetic trees are an estimate of genealogical relationships among groups of organisms. They are reconstructed by analyzing homologous nucleic acid sequences from different organisms and deriving an evolutionary relationship from the similarity in sequences. Ribosomal DNA consists of gene clusters tandemly repeated on a chromosome. Each cluster […]
