Outline and Purpose of the Course This class will introduce to students one of the most abundant forms of life on earth: the Nematodes or roundworms. The most famous of these is the useful model organism called Caenorhabditis elegans. The goal of the class is to provide both a survey of how scientists use these organisms to conduct research, demonstrate the worm's great importance to biology, and provide hands-on experience with simple worm manipulation.

Students will also learn directly about some of the current biological questions that are being addressed with this versatile model organism. We will also find wild nematodes around Kyoto, make scientific observations on them and use DNA sequencing to identify their species. Whether we find a new species, or identify new isolates of known ones, this class will introduce you to a new realm of life.

Course Goals -To understand the biology and diversity of nematodes
-To understand the uses of the nematode Caenorhabditis elegans in modern biological research
-To understand the anatomy and life cycle of C. elegans
-To learn how to create new strains containing desired mutations by designing crosses between animals
-To acquire the knowledge and experience needed to begin genetic research with C. elegans

11-12 Genome sequence of C. elegans and its relatives
13-14 Selected topics in nematode research and application to human health
15. Feedback
Evaluation Methods and Policy Evaluations will be based on participation, short quizzes, and either a final exam or a term paper. Each area will contribute 1/3rd of the total grade.
Course Requirements This is an introductory course. There are no requirements, but a basic familiarity with biology and genetics will be beneficial.
Study outside of Class (preparation and review) Students will have to understand technical vocabulary in English. This may require studying outside of class hours.
