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.
DNA and proteins are key molecules of the cell nucleus.
One gene makes one protein.
A gene is made of DNA.
Bacteria and viruses have DNA too.
The DNA molecule is shaped like a twisted ladder.
A half DNA ladder is a template for copying the whole.
RNA is an intermediary between DNA and protein.
DNA words are three letters long.
A gene is a discrete sequence of DNA nucleotides.
The RNA message is sometimes edited.
Some viruses store genetic information in RNA.
RNA was the first genetic molecule.
Mutations are changes in genetic information.
Some types of mutations are automatically repaired.
