BIOL 140: Intro to Molecular and Cell Biology

Discover the fascinating science behind table salt's unique characteristics that arise from the bond between sodium and chloride atoms. Explore topics like its unique taste, solubility in water, and ability to conduct electricity. Learn how the combination of sodium and chloride creates properties neither element possesses on its own.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

Discover the unique characteristics of cartilage, its critical roles in the human body, and the reasons behind its slow healing rate. Uncover myths and gain clarity on the essential factors influencing cartilage repair.

Explore the world of DNA replication by comparing it to climbing a staircase. Understand the roles of leading and lagging strands, and discover the importance of DNA Polymerase III in this intricate process.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.
