BIOL 101: Biological Science I

Unpack the concept of Restriction Fragment Length Polymorphism (RFLP), exploring the significance of DNA fragment variations. Learn how restriction enzymes act as molecular scissors, leading to insights into genetic disorders, biodiversity, and more.

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.

Discover the unique characteristics of the Mammalia class, with a focus on humans. Understand the critical role of molecular oxygen in our survival and the consequences of its absence. Learn how oxygen stands out among other vital factors like food, water, and nitrogen.

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Explore the intricate workings of the immune system's overactive responses, known as hypersensitivity reactions. Learn about the classification into Types I, II, III, and briefly, IV, along with real-world examples. Uncover the mechanisms behind these reactions and their impact on our health.

Explore the secrets of fossilization in sedimentary rocks. Uncover how these rocks, like nature's archives, preserve the history of life on Earth over billions of years. Delve into the unique processes that create these historical records.
