Barrett, The Honors College Thesis/Creative Project Collection
Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.
Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

To determine if the disruption of the MMR pathway results in the reduced conservation of methylated adenines as well as an increased tolerance for mutations that result in the loss or gain of new GATC sites, we surveyed individual clones isolated from experimentally evolving wild-type and MMR-deficient (mutL- ;conferring an 150x increase in mutation rate) populations of E. coli with whole-genome sequencing. Initial analysis revealed a lack of mutations affecting methylation sites (GATC tetranucleotides) in wild-type clones. However, the inherent low mutation rates conferred by the wild-type background render this result inconclusive, due to a lack of statistical power, and reveal a need for a more direct measure of changes in methylation status. Thus as a first step to comparative methylomics, we benchmarked four different methylation-calling pipelines on three biological replicates of the wildtype progenitor strain for our evolved populations.
While it is understood that these methylated sites play a role in the MMR pathway, it is not fully understood the full extent of their effect on the genome. Thus the goal of this thesis was to better understand the forces which maintain the genome, specifically concerning m6A within the GATC motif.
In other stories (wherein Paul tries—and often fails—to figure himself a secondary character), the tangled lives of his immediate social circle unravel, overlap, and disintegrate amidst the decaying milieu of the Scene and the maddening sprawl of Phoenix. A brief sampling of happenings: Sophie confronts ideological qualms with capitalism by way of a summer gig selling knives to depressed housewives; Brett nearly burns a house down on the Fourth of July; hallucinogenic kombucha is foisted upon a hapless Alex; black mold overtakes Paul’s residence; etc.
The core text is followed by an afterword supposedly written by (the perhaps psychotic) Saul P. Thomas Marton, Ph.D. and acts as an academic analysis of the nonexistent film adaption of Miserablists. There, Marton places Marston’s work in conversation with many influential critical text and works of fiction that shaped the formation of Miserablists (including Roland Barthes’ Lover’s Discourse, Slavoj Žižek’s The Plague of Fantasies, and Alain Robbe-Grillet’s Last Year at Marienbad).
