BIOL 352: Cellular Biology

Nucleic acids, comprising DNA and RNA, are vital biomolecules encoding genetic information. We explore the structure and components of their monomers, nucleotides, emphasizing the role of nitrogenous bases and the significance of polynucleotide chains in storing genetic data.

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

Discover how our brain interprets the scent of smoke differently based on context. Compare reactions in an open campfire setting versus an enclosed residence hall. Understand the underlying mechanisms of olfactory fatigue and context-driven alarm responses.

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.

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.

Explore the similarities and differences between the circulatory systems of amphibians and humans. Understand the distinctions in heart chambers, blood pressure, and where these two species align in their circulatory features.
