Topoisomerase Webinar with Joe Deweese

Topoisomerase II is an extremely important enzyme in your cells that is designed to untangle knots and supercoils in DNA strands that arise during replication and transcription. It does this by grabbing two tangled DNA segments, holding one steady while it breaks the other segment in two, and then passing the first segment through the break. The second segment is then reconnected, and the two DNA segments are released, having been successfully untangled. Without topoisomerases, chromosomes would become an impossible mess, making DNA replication, transcription, and cell duplication impossible.

The carefully orchestrated untangling activity of topoisomerase II doesn’t happen by accident. This enzyme is a molecular machine that only works because its amino acid sequence is highly specified to provide a special shape and structure necessary for its function. In other words, topoisomerase enzymes contain high levels of complex and specified information—a hallmark of intelligent design.

This webinar will premiere a new molecular machine animation on the topoisomerase enzyme. If you haven’t already, make sure to watch the previous molecular animations on our YouTube channel. The webinar will also feature Q & A with a topoisomerase researcher, Professor Joe DeWeese of Freed-Hardeman University, to talk about his own research and the amazing design of this enzyme. DeWeese will be interviewed by Casey Luskin, Associate Director of Discovery Institute’s Center for Science & Culture, for further details on this magnificent process. Concluding the interview, webinar attendees will have nearly 30 minutes to ask questions of DeWeese and Luskin regarding the topoisomerase enzyme.

Join us on Saturday, February 12th, at 10 AM PT (1 PM ET) for what should be a superb interview! The webinar is free, so register today!

Panelists


Joe Deweese

Joe Deweese received his BS in Biochemistry from Freed-Hardeman University and his PhD in Biochemistry from Vanderbilt University. For twelve years, he taught in the Department of Pharmaceutical Sciences at Lipscomb University. His teaching included biochemistry, molecular biology, genetics, anticancer pharmacology, and cellular physiology. Deweese is starting a new role in August, 2021 as Professor of Biochemistry and Director of Undergraduate Research at Freed-Hardeman University. His research interests include characterizing the mechanism of anti-cancer agents, especially those that target topoisomerase II. Recent studies from his lab have focused on etoposide metabolites, thiosemicarbazones, and natural product derivatives. Currently, his work is focused on examining the differences between the two versions of topoisomerase II found in humans. He and his wife, Liz, have two children.

Casey Luskin

Associate Director, Center for Science and Culture
Casey Luskin is a geologist and an attorney with graduate degrees in science and law, giving him expertise in both the scientific and legal dimensions of the debate over evolution. He earned his PhD in Geology from the University of Johannesburg, and BS and MS degrees in Earth Sciences from the University of California, San Diego, where he studied evolution extensively at both the graduate and undergraduate levels. His law degree is from the University of San Diego, where he focused his studies on First Amendment law, education law, and environmental law.
