BIOC 2580 (Fall 2009)
Final Exam Practice Package
This package will not be taken up in session; it is supplemental only.
Please work on it with friends, and use your course notes to get the
answers (all questions were generated from course notes).
This package was made much longer than a typical final exam – so don’t
use it to judge your timing. Several questions were simply generated so
that you may have additional practice.
Good luck on your final exam!!
