Essential Characteristics of Life

Mr. Andersen's video on Biology Essentials explores the tree of life, highlighting the shared characteristics of all life forms, such as the genetic code, central dogma, and metabolism. He explains how these features are conserved across the three domains of life: Bacteria, Archaea, and Eukarya. The video also delves into the complexity of eukaryotic cells, discussing the endomembrane system and endosymbiosis, which contribute to cellular complexity. The video emphasizes the universality of these biological processes and their origins from a common ancestor.
