Using The Flexon Approach To Rnai To Identify Essential Genes That Affect Gonadal Development In C. Elegans, Joyce S. Lefevers

Undergraduate Theses

To elucidate the molecular role of essential genes in the gonadal development of Caenorhabditis elegans (C. elegans) it is necessary to utilize specialized molecular techniques such that the phenotypic effects of gene knockdown can be studied while the viability of the organism is preserved. Shaffer and Greenwald (2022) developed the floxed exon (flexon), a tool that improves upon previous approaches to spatiotemporal control of gene expression. The flexon subunit is made up of an artificial exon with a stop cassette flanked by artificial introns which, when inserted into a gene of interest, prevents the expression of that gene. …

Covid Minds: A Thematic Review Of The Pandemic On Neural Mechanisms And Political Polarization, Madison Jeffries

Honors Projects

This paper analyzes how the COVID-19 pandemic influenced political polarization in the United States by examining the interactions between social system disruption, psychological stress, and underlying neurological behaviors. While previous research has extensively discussed pandemic's influence on public health and societal breakdowns, studies fail to examine how these disruptions shaped political divisions. This study synthesizes interdisciplinary literature on pandemic-induced stressors and analyzes factors, including institutional mistrust and social isolation, and how these experiences shape political behavior and perspectives. Applying research from psychology and neuroscience, the paper argues that prolonged exposure to pandemic-related stressors changed neurological and behavioral patterns in response …
