Studying Human Disease Genes In Caenorhabditis Elegans : A Molecular Genetics Laboratory Project, Elisabeth A. Cox-Paulson, Theresa M. Grana, Michelle A. Harris, Janet M. Batzli

Biological Sciences Research

Scientists routinely integrate information from various channels to explore topics under study. We designed a 4-wk undergraduate laboratory module that used a multifaceted approach to study a question in molecular genetics. Specifcally, students investigated whether Caenorhabditis elegans can be a useful model system for studying genes associated with human disease. In a large-enrollment, sophomore-level laboratory course, groups of three to four students were assigned a gene associated with either breast cancer (brc-1), Wilson disease (cua-1), ovarian dysgenesis (fshr-1), or colon cancer (mlh-1). Students compared observable phenotypes of wild-type C. elegans and C. elegans with a homozygous deletion in the assigned …
