About the lecture

In the first mini-lecture, we are introduced to the structure of DNA, and the principle behind why repairing any damage to it is so important. We learn about the different types of damage and mutation that can occur to DNA, including silent and deleterious mutations. We move onto some of the enzymes involved in the synthesis of new DNA strands, as well as some of the mechanisms available to a cell when it needs to repair strands of DNA. To finish off this lecture, we learn about x-ray crystallography, a unique method used often in Biology and Chemistry that has allowed us to see DNA and its repair mechanisms at an atomic-scale resolution.

About the lecturer

Professor Karl Haushalter is Professor of Chemistry and Biology and Department Chair of Chemistry at Harvey Mudd College. He studies the details of DNA repair, providing an entry point into understanding the molecular mechanisms of carcinogenesis, aging, and evolution. In addition to these scientific pursuits, Prof. Haushalter is active in community efforts to combat the stigma associated with HIV-AIDS and support those living with HIV-AIDS through education and empowerment.
