Kimbrell, Section of Molecular and Cellular Biology [email protected], 752-1116 Office Hours: T Th 11:00am-noon, 3114 Life Sciences, and by appointment Teaching Assistants: Jeffrey Myers [email protected] Office Hours: M 3:00-4:00pm, F 2:30pm-3:30pm, 3061 SLB Adam Ross [email protected] Office Hours: M noon-1:00pm, W 11:00am-noon, 3061 SLB General: The goal of this course is to provide an understanding of the fundamental concepts of genetics, both classical and molecular. This course will reinforce material you have received from previous courses, expand your knowledge into new areas, and enable you to proceed to more advanced courses with greater understanding. Analytical problem solving is integral to the study of genetics. Although there is much to memorize, the concepts of genetics cannot be mastered by simple memorization. You must actively solve genetics problems. In order to learn how to do this, work through the “Integration” and “Solved” problems at the end of each textbook chapter, then solve the additional problems that are assigned. The best way to do well in this class is to attend lecture, read the text, and solve the suggested problems. And, of course, ask questions. The TAs and I look forward to working with you as you learn genetics in this Genes and Gene Expression course. The website for this course can be accessed through SmartSite. Check this site daily for course information and other materials. Grading: Grades will be based on classroom participation (20 points), two midterms (110 points each), and a final exam (160 points) for a total of 400 points. The historical average for BIS101 classes has been a C/C+. Exams are given in class, and there will be no early, late or makeup exams. If an exam is missed and the absence is verified by a medical form from a treating physician, or other valid excuse with documentation, then the score will be calculated based on the other exams taken. If no valid documentation is received, a zero will be given for the missed midterm. Regrade requests for the midterm exams are filed in 156 Briggs Hall. To be considered, the petition must be filed no later than one week after the exam is returned and the exam must have been written in pen. The entire exam will be regraded upon filing a petition. Please file a regrade petition in the case of errors in adding up points earned. These exams can be in pen or pencil. According to University policy, final exams cannot be regraded.
