Kaylee Sill (McElroy) and Dr. Robert Davis, Physics and Astronomy Determining properties of DNA and RNA, such as conductivity of the strands, could be essential in the development of bioelectronics. Both DNA and RNA have pi bonds, which form when an electron is ‘shared’ between multiple atoms. The electrons forming pi bonds may be able […]

The Electronic Properties of DNA
Richard Marsh and Dr. James P. Lewis, Physics and Astronomy In the world today there is an immense interest in the field of nanotechnology. One particularly unique aspect is molecular electronics. The ability to take one molecule and use it as a transistor has vast applications. While the transistors on our current computers are on […]
Correctly Assigning DNA Barcodes to Organisms
James B Finlay and Dr. Keith A. Crandall, Integrative Biology Harvard biologist Edward O. Wilson suggested that what makes humans unique is our innate need for closeness to other forms of life. This “biophilia” has been evident since recorded history and was brought to the forefront of science with Darwin’s famous writings about the origin […]
The effects of point mutation saturation on the loss of information in mutated DNA sequences
Kimberly Baer and Dr. David McClellan, Integrative Biology The research I am conducting fills a niche in molecular adaptation. My experiment uses accepted methods of reconstruction to evaluate the accumulation of multiple hits at single sites. It is accepted that over time point mutation saturation in specific sequences occurs in a clock-like manner following Poisson-like […]
MITOCHONDRIAL DNA ANALYSIS OF THE INHABITANTS OF AMANTANI, PERU
Matthew A. McNairy and Dr. David Hart, Chemistry and Biochemistry Mitochondrial DNA (mtDNA) is useful in population genetics studies because it is inherited only from the maternal parent. Because there is no paternal contribution and no recombination, mtDNA represents a clear maternal lineage. Four predominant maternal lineages or mitochondrial haplotypes have been found to exist […]
DNA as a Potential Molecular Nanowire
Richard Marsh and Dr. James P. Lewis, Department of Physics and Astronomy In the world today there is an immense interest in the field of nanotechnology. One particularly unique aspect is that of molecular electronics. The ability to take one molecule and use it as a transistor has many applications. While the transistors on our […]
THE EFFECTS OF BRYOSTATIN I ON THE PROGRESSION OF PAPILLOMAVIRUS DNA-INDUCED TUMORS
David J. Hoopes and Drs. Richard Robison & Beverly Roeder, Microbiology The bryostatins are a unique family of at least 13 naturally occurring macrocyclic lactones which have demonstrated considerable anti-neoplastic activity. Bryostatin 1 was isolated by G. R. Pettit from the marine bryozoan Bugula neritina. B. neritina is a colonial filter-feeder commonly know as a […]
Characterization of a cDNA Encoding β-amyrin Synthase Involved in Saponin Biosyntheses in Chenopodium quinoa
Derrick J. Reynolds and Dr. P. Jeff Maughan, Plant and Animal Sciences Quinoa (Chenopodium quinoa Willd) is an important crop for subsistence farmers in the Altiplano (high plains) of Peru, Bolivia, and Argentina. Quinoa has the potential to be an effective crop for many temperate and highland-tropical regions due to its ability to thrive in […]
Characterization of a DNA Helicase Gene that Targets Sub-cellular Organelles in Arabidopsis thaliana
Logan Hazard and Dr. Brent Nielsen, Microbiology and Molecular Biology DNA helicases are essential to the development of all living organisms. The function of these proteins is to temporarily separate duplex DNA, allowing for transcription, replication, recombination, and repair to take place. The Pif1p subfamily of helicases found in yeast specifically targets sub-cellular organelles, notably […]
Characterization of a cDNA Encoding β-amyrin Synthase Involved in Saponin Biosyntheses in Chenopodium Quinoa
Derrick J. Reynolds and Dr. P. Jeff Maughan, Plant and Animal Sciences Quinoa (Chenopodium quinoa) is an important crop for subsistence farmers in the Altiplano (high plains) of Peru, Bolivia, and Argentina. Quinoa’s seed is highly nutritious, but the seed coat of quinoa contains several anti-nutritive triterpenoid saponin compounds. The biological role of saponins in […]
