BIOL 207: Intro to Biology

In this video, we explore the crucial role of the cytoplasm in a cell and its division. By drawing parallels to intriguing concepts like telekinesis, we shed light on vital processes like karyokinesis and cytokinesis. By the end, we unveil cytokinesis as the primary method for plant cell cytoplasm division.

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 groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution

Discover the critical role iodide ions play in regulating metabolism through their involvement in thyroid hormones. Learn how active transport enables the movement of these ions in the body, requiring ATP energy. Uncover common sources of iodide ions and their importance in medical applications.

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 captivating Oparin-Haldane hypothesis, detailing the three key steps in the journey from non-life to life. Witness the emergence of organic molecules through non-biological processes, the formation of complex molecules, and the ultimate leap to self-replicating DNA. Join us on this scientific exploration of life's origins.
