Engaging Students In A Genetics Course-Based Undergraduate Research Experience Utilizing Caenorhabditis Elegans In Hybrid Learning To Explore Human Disease Gene Variants, Natalie Forte, Virginia Veasey, Bethany Christie, Amira Carter, Marli Hanks, Alan Holderfield, Taylor Houston, Anil Challa, Ashley Turner

Research, Publications & Creative Work

Genetic analysis in model systems using bioinformatic approaches provides a rich context for a concrete and conceptual understanding of gene structure and function. With the intent to engage students in research and explore disease biology utilizing the nematode Caenorhabditis elegans model, we developed a semester-long course-based undergraduate research experience (CURE) in a hybrid (online/in-person) learning environment—the gene-editing and evolutionary nematode exploration CURE (GENE-CURE). Using a combination of bioinformatic and molecular genetic tools, students performed structure-function analysis of disease-associated variants of uncertain significance (VUS) in human orthologs. With the aid of a series of workshop-style research sessions, students worked in teams …

Mystery Mutt: Dna Analysis With A Dog Named Charlie, Kelly M. Jones

Inclusive Strategies for Teaching Secondary Mathematics and Science

This article provides an in-depth exploration of the design, execution, and outcomes of the "Mystery Mutt: DNA analysis with a dog named Charlie" lesson. Designed for seventh-grade life science students, the lesson focuses on unraveling the correlation between genotype and phenotype using authentic pet DNA test results. Grounded in real-life experiences and employing a multi-dimensional approach, the lesson successfully bridges the gap between theoretical genetic concepts and practical applications. The article discusses the lesson's alignment with academic standards, consideration of materials and safety, its unique classroom context, and the engaging phases of exploration, explanation, elaboration, evaluation, and closure. The emphasis …

The Presence Of Childhood Obesity In Nebraska And The Physiological Repercussions Of The Disease, Madison R. Bezousek

Honors Theses

Childhood Obesity can cause lifelong repercussions in children and adults. There has been stigma around the causes of obesity and its relation to lifestyle choices, without consideration of the genetic and syndromic causes. In this literature review the causes of obesity were investigated, along with the effect on the physiological systems and the enviornmental factors that are continuing the obesity epidemic. Preventing and treating lifestyle obesity is something that is seen to have the greatest effect on youth, especially with intergenerational obesity. Nebraska schools have implemented programs to encourage healthy living, and ongoing research is being implemented to reduce the …

Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi

Honors Theses

All populations display patterns in allele frequencies over time. Some alleles cease to exist, while some grow to become the norm. These frequencies can shift or stay constant based on the conditions the population lives in. If in Hardy-Weinberg equilibrium, the allele frequencies stay constant. Most populations, however, have bias from environmental factors, sexual preferences, other organisms, etc. We propose a stochastic Markov chain model to study allele progression across generations. In such a model, the allele frequencies in the next generation depend only on the frequencies in the current one.

We use this model to track a recessive allele …
