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. Biology 320L or Molecular Biosciences 320L may not both be counted. One lecture hour and five laboratory hours a week for one semester.
