BIOL 219: Techniques in Molecular 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 definitions of tissue, organ, and organ system. Understand the distinctions and interconnectedness between these components. Get an overview of the human body's eleven major organ systems and their functions.

In this video, we explore the crucial role of the cytoplasm in a cell and its division. By drawing parallels to intriguing concepts like telekinesis, we shed light on vital processes like karyokinesis and cytokinesis. By the end, we unveil cytokinesis as the primary method for plant cell cytoplasm division.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Discover the body's innate ability to adapt to extreme cold conditions. Learn how the brain orchestrates warming responses like shivering. Grasp the concept of homeostasis in maintaining internal stability.

Unravel the mysteries of food chain lengths by analyzing various factors. We spotlight the 10% rule in ecology, emphasizing how energy transfer inefficiencies mold ecosystem structures and functions.
