Genetics, classically defined as the study of heredity, has evolved into a discipline whose limits are continually expanded by innovative molecular technologies. This course covers the experimental basis for our current understanding of the inheritance, structures, and functions of genes. It introduces approaches used by contemporary geneticists and molecular biologists to explore questions about aspects of biology ranging from embryonic development to aging. The laboratory part of the course provides an experimental introduction to modern genetic analysis. Laboratory experiments include linkage analysis, bacterial transformation with plasmids, DNA restriction mapping, and computer-based cloning. Format: lectures/laboratory, six hours a week. Evaluation will be based on hour exams, a final exam, laboratory reports, and problem sets. Prerequisites: Biology 101 and 102. No enrollment limit (expected: 85).
