BIOL 4620: Undergraduate Seminar

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.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.

Explore the influential Three-Domain System of classification, introduced by Carl Woese in 1978. Discover how it categorizes life into Bacteria, Archaea, and Eukarya based on distinctive cellular structures. Learn about the characteristics of each domain, from prokaryotic Bacteria and Archaea to the rich diversity within Eukarya, encompassing Protists, Fungi, Plants, Animals, and the unique world of viruses.

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.

Unravel the intricacies of mitosis by identifying each phase and their characteristics. Highlight the process that is not a part of mitosis, emphasizing the importance of DNA replication.

Discover the multifaceted role of cytokines as the body's cellular messengers. Uncover their pivotal tasks in regulating immune and inflammatory responses. Dive into their significance in cell growth, differentiation, and inter-cellular communication.
