Concept 26 RNA was the first genetic molecule.
Ray Gesteland is a Distinguished Professor of Human Genetics in the Department of Human Genetics at the Eccles Institute, University of Utah. His research is on RNA, specifically secondary structures in RNA that can provide additional coding information.
- RNA function -- the code within the code.
- Why DNA was probably not the driving force of molecular evolution in a pre-biotic environment.
- RNA 'instability.'
- Differences between DNA and RNA and the evolutionary roles carried out by each molecule.
- The pre-biotic soup of life and the need to increase molecular concentrations.
