Part 1: The Roles of Telomeres and Telomerase

This lecture from the iBioSeminars project is presented by Elizabeth Blackburn from the University of California, San Francisco Department of Biochemistry and Biophysics. It covers telomerase, a specialized ribonucleprotein reverse transcriptase, important for long-term eukaryotic cell proliferation and genomic stability because it replenishes the DNA at telomeres. This video is the first of three parts, running 48:27 minutes and can be downloaded in QuickTime, MP4, M4V, or PDF formats.
