BISC 207025: Biology

Explore the foundational processes of aerobic and anaerobic respiration. Uncover the key roles of glycolysis, the citric acid cycle, and oxidative phosphorylation. Differentiate between the efficiencies and electron acceptors of both respiration types.

Unravel the intricate relationship between histones and DNA. Learn how histones maintain DNA structure within the cell nucleus and understand the significance of charge attractions in DNA-histone binding.

Explore the role of human placental lactogen (hPL) in this informative video. Learn how hPL prepares the breasts for lactation, debunking other hypotheses about its functions in nourishing the placenta or regulating the menstrual cycle. Discover the primary function of this remarkable placental hormone.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.

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.
