Concept 24 The RNA message is sometimes edited.
Rich Roberts is Director of Research for New England Biolabs, one of the first commercial sources for restriction enzymes that is today a leading supplier of molecular biology reagents.
Phil Sharp is the Salvador E. Luria Professor of Biology at the Massachusetts Institute of Technology. His laboratory studies both the catalytic processes responsible for splicing and the nature of the factors conferring specificity.

- Describing the early work purifying restriction enzymes.
- Describing the early experimental evidence for 'interrupted' RNA transcripts that went on to suggest the subsequent electron micrograph studies.
- Describing the set up of the electron micrograph experiments.
- Performing the electron micrograph DNA/RNA hybridizations, and seeing the results.

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.
