Intended for those engaged in original laboratory research at an advanced level. This course number is most frequently elected by senior Honors students who have completed MCDB 300 and who are completing their research and writing their thesis. A final paper is required. (Refer to the description of MCDB 300 for more information.) The work in this course may continue for two semesters. A 'Y' grade can be reported at the end of the first-term to indicate work in progress. At the end of the second term of MCDB 400, the final grade is posted for both term's elections. Students interested in MCDB 400 should obtain the brochure MCDB Department Policies on Undergraduate Research from the Undergraduate Biology Program Office (1111 Natural Science Bldg).
