S5E4: Endosymbiosis - How Complex Cells Came to Be

C6E8: DNA Replication - Copying the Code

Chapter 6, Episode 8 In this episode we'll discuss the process of DNA replication and point out the subtle differences between linear chromosomes and circular chromosomes and how they are replicated. We'll also cover the important enzymes involved in this process, and how proofreading prevents mutations.

C6E7: The Genome

Chapter 6, Episode 7 In this episode, we'll review the DNA molecule in detail, talk about how chromosomes are organized in prokaryotic and eukaryotic cells, and discuss how this organization sets cells up for replication.

C5E6: Protists and Helminths

Chapter 5, Episode 6 In this episode we finish the chapter on eukaryotes by discussing algae, protozoa and helminths. We review the life cycle of Plasmodium, the protozoa that causes malaria, and cover the different classifications of helminths.

C5E5: The Fungus Among Us

Chapter 5, Episode 5 In this episode we explore the characteristics of microorganisms belonging to the kingdom of fungi. What makes them unique, what their morphologies are, the similarities between fungal cells and human cells, and the differences between fungal cells and bacteria. We also briefly touch on mycoses, the fungal pathogens, and end the episode with the benefits of fungi to humans and to our environment.

S5E4: Endosymbiosis - How Complex Cells Came to Be

Chapter 5, Episode 4 This episode introduces the Endosymbiotic Theory and explains how complex eukaryotic cells evolved from prokaryotic ancestors. We briefly review the major groups of microbial eukaryotes and highlight the structural features, including mitochondria, chloroplasts, and membrane-bound organelles, that distinguish them from bacteria and influence how we treat eukaryotic pathogens.
