BIOL 204: Principles of Biology

Discover how the protein coat from pathogenic cells can transform nonpathogenic cells, the surprising role of heat-killed pathogenic cells in causing pneumonia, and the transfer of pathogenic traits from one cell to another. Join us on this journey of scientific exploration as we unravel the mysteries of bacterial transformation and more.

Venture into the intricate mechanisms of a eukaryotic cell as we clarify the conditions under which transcription begins. Discover the pivotal role of the promoter and the essential docking of transcription factors.

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Discover how humans adapt to cold environments through thermoregulation processes. Understand the body's heat conservation and generation mechanisms. Learn why certain physiological responses occur in cold conditions.

Unravel the origins of blood cell types as we differentiate between myeloid and lymphoid stem cells, highlighting the unique lineage of platelets, B cells, and Natural Killer cells.

Explore the intricate workings of the immune system's overactive responses, known as hypersensitivity reactions. Learn about the classification into Types I, II, III, and briefly, IV, along with real-world examples. Uncover the mechanisms behind these reactions and their impact on our health.
