This project was prepared as part of a BioQUEST faculty development workshop entitled BioQUEST 2004 Summer Workshop for Undergraduate Faculty: Systems Biology at Beloit College in June 2004. The BioQUEST Curriculum Consortium is committed to the reform of undergraduate biology instruction through an emphasis on engaging students in realistic scientific practices. This approach is sometimes characterized as an inquiry driven approach and is captured in BioQUEST's three P's (problem-posing, problem-solving, and peer-persuasion). As part of this workshop groups of faculty were encouraged to initiate innovative curricular projects. We are sharing these works in progress in the hope that they will stimulate further exploration, collaboration and development. Please see the following links for additional information:

Possible Audiences:

Tools presented in the problem space can be used for in-class projects in introductory biology classes. More complex questions could be carried from introductory biology to more advanced biochemistry, molecular biology and evolution classes. Undergraduate students could also use this as a starting point to develop independent research projects.  

 
 


Brief Overview:

Prions are infectious protein particles associated with various neurodegenerative diseases in humans and animals. This problem space introduces basic skills in protein structure and sequence exploration that can be used to analyze some unusual properties of prions, and develop testable hypotheses that can be explored through these tools. Students will be challenged to use a systems-biology approach to link structure, evolution and function of proteins.
