C5E6: Protists and Helminths

C6E13: Mutations

Chapter 6, Episode 13 This episode explains how mutations alter DNA sequences, including point mutations, insertions, deletions, and frameshifts, and how these changes can affect protein function and phenotype. It also discusses mutagens, DNA repair mechanisms, and the biological significance of mutation in genetics, disease, and microbiology.

C6E12: Gene Transfer - Sharing is Caring

Chapter 6, Episode 12 This episode discusses the unique ways bacteria evolve through DNA. They transfer genetic material horizontally, within the same generation, and the processes by which this is accomplished are discussed in the episode.

C6E11: Gene Regulation and Operons

Chapter 6, Episode 11 This episode introduces the operon, and discusses how bacterial cells control gene expression. The lac operon is discussed in detail as an example of the ways bacteria conserve energy and only make proteins when they are necessary for survival.

C6E10: The Central Dogma - Translation

Chapter 6, Episode 10 This episode is a continuation of the central dogma, focusing on the process of translation and how ribosomes create proteins from messenger RNA.

C6E9: The Central Dogma - Transcription

Chapter 6, Episode 9 This episode introduces the central dogma and the genetic code. We'll discuss how cells create protein from genes, and point out the differences in the process of transcription between eukaryotic and prokaryotic cells.
