This week's seminar was brought to us by Benjamin Bradsen. Bradsen is a PhD candidate at the University of Illinois Urbana-Champagne. The title of his presentation was “DNA as a Catalyst Towards the Development of Artificial Proteases.” The primary purpose of this discussion was the role DNA can play as a catalyst for proteases. DNA is also known as deoxyribonucleic acid and is a molecule that encodes the genetic instructions used in the development and function of all known living organisms. While enzymes are large biological molecules that assist in many metabolic processes.
