Explore the complex structures and functions of cells through direct observation and experimentation. Discuss regulation of gene transcription and translation, protein sorting, organelles and membrane trafficking, cytoskeletal dynamics, and cell division. Use a combination of modern molecular biology, biochemistry, and microscopy techniques, with a strong emphasis placed on hypothesis-driven approaches, proper experimental design, and clear scientific writing and presentation. One lecture hour and five laboratory hours a week for one semester. Biology 320L or Molecular Biosciences 320L may not both be counted. Prerequisite: The following with a grade of at least C-: Biology 325 or 325H, and Biology 206L, Integrative Biology 208L (or Biology 208L), Molecular Biosciences 226L (or Biology 226L), or Environmental Sciences 311.
