BIO 181 Lecture 3.6

Lecture 3.5: Cancer


Why is the Central Dogma important? Why are we spending so much time learning about transcription and translation? This lecture will help answer that question. Cancer is one of the most significant diseases in human history. It was recognized by Aristotle around 350 B.C.E., and even today it is the second leading cause of death worldwide. Nevertheless, our ability to treat this disease successfully has improved a great deal over the last 20 years. That improvement came only after our understanding of the molecular mechanisms of gene function, the very same mechanisms that we have studied in this unit. This lecture will open the door to the deeper world of application of our basic biological knowledge.
