Unformatted text preview: Bio 315 - Cell Biology: Introduction Announcements, lecture notes, assignments, supplementary material, old exams will be posted on NU Blackboard web site Note: I always put in more slides than I expect to get to in case things happen to go unexpectedly fast. Download and read syllabus from NU Blackboard site. No lecture on Jan 21 MLK Day, no discussion that week. TAs are Victoria Church, Vivian Hernandez, Kara Nordin and Austin Rice. TAs and Prof. Beitel have office hours. Were here to help. Format Lectures (Exams 3 @ 26.7% each) Attendance at lectures is expected.

During discussion section, TA will present the first paper, after that students will present (4 sessions). Please ask LOTS of questions. Participation counts!
