Filamentous Bacterioviruses: Nanoparticles Formed with the Help of a Zippper-like Protein

Presented by Dr. Donald Gray.

April 3, 2006 at 7 p.m.
UTD Conference Center (CN1.212)

Sponsored by The Department of Molecular and Cell Biology, the Center for Science/Mathematics Education Research, and Sigma Xi.

"Long filamentous viruses that infect bacteria have diameters of less than 10 nm and are examples of natural nanoparticles. In their life cycles, these viruses produce a marvelous small protein that is able to zip up a circular strand of DNA into a filament, which is necessary in order to form the final viral structure. How does the protein zipper start? I will describe an unusual DNA structure called a quadruplex that is one type of zipper start. It was discovered using an in vitro laboratory method of chemical evolution."

This presentation is designed to give teachers new information relating to the Nature of Science, Organization of Living Systems, and Interdependence of Organisms that can be woven into current curricula. Teachers will receive two hours of professional development credit.

Dr. Gray’s presentation is free and open to the public.
