This kind of potentially life-saving research wouldn't be possible today if not for science conducted by Walter Gilbert and Frederick Sanger. The pair was awarded the 1980 Nobel Prize in Chemistry for work on sequencing the base pairs, or chemical letters, that make up DNA and RNA. The work has since allowed scientists to sequence the unique genomes of numerous animals—including humans.
"Without their discovery, the entire genomics revolution would be impossible," Tritton said. "The dream of personalized genomic medicine traces back to this discovery."...
