The course will examine these topics from the perspective of current research in molecular biology, and pathologies that may be associated with dysfunction The text and instructor will provide background information necessary for a more complete understanding of the topics discussed. Required Texts 1. Molecular Biology of the Cell, 4th ed. by Alberts et al., ISBN # 0-8153-3218-1. This comes with a CD “Cell Biology Interactive” that has lots of cool animations related to topics covered in each chapter of the text – this is a great study resource. 2. Dictionary of Cell and Molecular Biology. 3rd edition. JM Lackie and JAT Dow. Academic Press, San Diego, CA., 1999. 3. Lab Manual (available at Basin Reproduction, 1437 E. 2nd Ave, 247-5212; call 24 hrs ahead so they have it ready when you come to pick it up). 4. Packet of journal articles (also available at Basin Reproduction). 5. Powerpoint slides – will be posted on website Grading Lab Work (20% of final grade): Assignments may include pre-lab questions, lab reports, data analysis. Questions on Papers (50% of final grade): variable points. We will read a set of primary journal articles and other related materials about once every 10 days. Questions on these papers will be due on the day of class discussion of the paper. You will receive a 0 if you are not in class to participate in the discussion, and are not ready to turn in your answers to questions on the article at that time. You may drop the lowest grade for one of these sets of questions. Short Quizzes/Homework/In Class Activities (15% of final grade): variable points. Course participation will be evaluated on days when paper discussions occur and when we solve problems in class. All students should be ready and willing to contribute information regarding their understanding of the paper being discussed, including material not necessarily found within the text of the paper (eg. more details regarding techniques used, results presented, etc.). Paper presentation (15% of final grade): 100 points. This will be a student-lead discussion of a paper you choose. The paper will need to be approved by the instructor and be available to the rest of the class, one week prior to your presentation. Your group (no more than 3 people) will make up a set of questions to be answered by the rest of the class. These questions must also be approved by the instructor and be available to the class one week prior to your presentation Final grades will be based on a 90%-80%-70%-60%-50% scale, with no curving. 90%+ = A, etc. All assignments must be typewritten, with computer-generated tables and graphs imported appropriately into the text. Web resources are a fine starting point, but should not replace peer-reviewed, library resources. Homework (questions on papers assigned) and labs must be turned in on time for full credit. There will be 5% loss in possible points per day late. No late assignment will be accepted after the instructor has graded and turned that assignment back. As with any course, plagiarism of any written or other assignment will result in a failing (F) grade. Students with disabilities have equal access and equal opportunity in this course. If you require reasonable accommodations to fully participate in course activities or meet course requirements, you must register with Disability Services, 280 Noble Hall, 247-7459. If you qualify for services, bring your letter of accommodation to me as soon as possible. Syllabus This is a tentative syllabus. Please come to class for the most up-to-date information.
