BIOL 3200: Introductory Genetics

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

Discover the significance of protobionts in the evolution of life, acting as a bridge from non-living to living entities. Understand their boundary formations akin to cell membranes and their rudimentary replication methods. Gain insights into the pivotal role they played in life's origin story.

Learn about the unique adaptability of facultatively anaerobic cells in different oxygen conditions. Discover the outcome of an experiment comparing their growth in aerobic and anaerobic environments. Grasp the resilience of these cells and their growth mechanisms.

Uncover why flamingos, genetically predisposed to white feathers, sport a pink hue. Dismissing influences like weather and DNA mutations, the mystery unravels with diet: the intake of carotenoids from their food which overrides their genetic blueprint

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.

Explore the intricate process of protein synthesis understanding how tRNA anticodons correspond with mRNA codons. Discover the role of ribosomes in reading mRNA sequences and how tRNA ensures the accurate translation of amino acids. Breakdown of mRNA-tRNA binding for efficient protein formation.
