BIOL 320: Principles of Ecology

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.

Discover the role of Okazaki fragments in DNA replication and the importance of DNA Ligase in ensuring their correct joining. Learn how a malfunction in this enzyme might disrupt the formation of continuous DNA strands on the lagging strand.

Explore the fundamental characteristics of anions and decipher the statements that define them. Understand how electron transfer leads to ion formation, creating atoms with net electrical charges. Learn about the key property that sets anions apart from other atomic entities, providing insights into atomic structure and charge.

This video provides a comprehensive explanation of mucous and serous membranes, defining their characteristics and addressing statements about their epithelial types, functions, and exceptions.

Explore the characteristics that distinguish normal cells from cancer cells in this informative video. Learn how normal cells perform specialized functions for overall health, while cancer cells grow uncontrollably. Discover why cancer cells lack differentiation, ignore reproduction control signals, and their connection to the absence of radical scavengers, all leading to their uncontrolled proliferation.
