Order these steps to build a strong “is it alive?” argument for any novel case (start with step 1).

  • State the criteria you will use (cell theory + several properties of life)

  • Argue the strongest “alive” interpretation and the strongest “not alive” interpretation

  • Identify which criteria are unmet or unclear, using specific evidence

  • Identify which criteria are clearly met, using specific evidence

  • Conclude with a qualified claim (e.g., alive, not alive, or borderline) and justify it by weighing multiple criteria

About this course

This course builds a coherent foundation in cell biology by connecting cell structure to function across molecular, organellar, and systems scales. Topics include cell theory; prokaryotic versus eukaryotic organization and evolutionary origins; macromolecules and enzyme principles; membrane structure, dynamics, and transport; the endomembrane system and organelle roles; bioenergetics in mitochondria (and chloroplasts overview); information flow from DNA to RNA to protein with protein targeting; mutations and multilayer gene regulation; signaling networks and feedback; the cell cycle, division, apoptosis, and cancer links; cytoskeleton-based transport and motility; cell interactions in tissues; and essential experimental methods and data interpretation.
