Our bodies love processing glucose, the primary energy source for many organisms. It is simple and easy to extract the energy contained within this simple sugar. But, there are other sugars that organisms can utilize such as lactose. One way that E. coli and many other bacteria harness lactose as an energy source is with the help of the lac operon. This episode explores the components of the lac operon and how the operon functions under varying levels of lactose and glucose.

In the early 2000s, news headlines were all reporting of the same terror: ricin laden letters. Once a person comes in contact with ricin and the poison is absorbed, cells lose the ability to perform translation. Without translation, the body is unable to synthesize proteins critical for life. In today’s episode, we will explore the step by step process of translation along with the structural components involved (ribosomes and t-RNA).

DNA serves as the genetic blueprint for all living organisms. They hold all of the information that govern our very existence. Our growth and development as living organisms relies on this essential biological molecule. In this episode, we will be explore the structure of DNA. Specifically, we will analyze nucleotide structure, dehydration synthesis, complementary base pairing, and the double helix.
