An upper-level genetics research course was developed to expose undergraduates to investigative science. Students are immersed in a research project with the ultimate goal of identifying proteins important for chromosome transmission in mitosis. After mutagenizing yeast Saccharomyces cerevisiae cells, students implement a genetic screen that allows for visual detection of mutants with an increased loss of an ADE2-marked yeast artificial chromosome (YAC). Students then genetically characterize the mutants and begin efforts to identify the defective genes in these mutants. While engaged in this research project, students practice a variety of technical skills in both classical and molecular genetics. Furthermore, students learn to collaborate and gain experience in sharing scientific findings with others in the form of written papers, poster presentations, and oral presentations. Previous students indicated that, relative to a traditional laboratory course, this research course improved their understanding of scientific concepts and technical skills and helped them make connections between concepts. Moreover, this course allowed students to experience scientific inquiry and was influential for students as they considered future endeavors.
