One of the basic components that support life are macromolecules with the four being carbohydrates, lipids, proteins, and nucleic acids. This podcast dives into the structure, function, and application of all of these macromolecules. In addition, we will also be discussing dehydration synthesis, hydrolysis, monomers, and polymers in order to have essential background information to understand macromolecules. 

Darwin's Theory of Natural Selection has served as a basis to this day for the reasoning behind evolution. It has assisted us to answer our largest questions concerning how and why species look the way they do. In this episode, we explore Darwin's voyage on the HMS Beagle, the five major points on his theory of natural selection, and Lamarck's views on evolution and why they are incorrect.

Every living organism you have ever seen has been the result of evolution. If we were to look back on humans millions of years ago, we would have looked drastically different compared to how we look today. In this episode, we discuss the five main factors that contribute to evolution: Genetic drift, gene flow, mutations, non-random mating, and natural selection. We explore the effects each factor and examples of how they allow a population to undergo evolution. 

The road to discovering the genetic material of cells, DNA, was a long journey. In this episode, we explore the three experiments that led to this discovery: The Griffith experiment, The Avery–MacLeod–McCarty experiment, and the Hershey Chase experiment.

Cells live in an ever-changing environment, always needing to be aware of their surroundings and reacting to an organism's needs. In order to understand when to take action, cells must receive a message from the outside world in a process called reception. Reception is the first of three steps in cell signaling. In this episode, we review how signaling molecules bind to receptors inside and outside of the cell, along with covering specific cell surface receptors like the G protein-coupled receptors, tyrosine kinases, and ion channel receptors.
