A study of the structure and functions of eukaryotic cells. Topics explored include the evolution of cells, basic biochemistry of biological macromolecules, recombinant DNA technology, gene expression, cell membranes, protein sorting in the secretory and endocytic pathways, cell metabolism, cell signaling, the cytoskeleton, the cell cycle, the extracellular matrix, cancer cell biology, and stem cells. Labs develop general lab skills, emphasize hands-on learning of methods and research concepts in cell biology (e.g. microscopy, SDS-PAGE, cell culture, etc.), and use the primary literature. Prerequisites: BIOL 121 and BIOL 123. Counts on the biology major in the cell and molecular group.
