A one-semester, introductory survey of cellular and molecular biology emphasizing scientific reasoning, quantitative analysis, and core laboratory/methods. Topics include chemistry of life; biomolecules and enzymes; cell structure, organelles, and microscopy; membranes, transport, and basic electrophysiology; metabolism and energetics (glycolysis through oxidative phosphorylation, fermentation, photosynthesis overview); DNA structure, replication, and repair; gene expression and regulation, epigenetics, and noncoding RNAs; genetics and population genetics; cytoskeleton, trafficking, and motility; cell communication, signaling networks, and cell cycle/mitosis/meiosis, apoptosis, and cancer; evolution and endosymbiosis; and cellular bases of physiology. Modern applications highlight omics, CRISPR, model organisms, bioinformatics, data visualization, and ethical considerations.
