Mutations are changes in genetic information.
Seymour Benzer used genetics to prove that mutations were caused by changes in the DNA sequence.
Seymour Benzer and his pet fly, 1974.
Alfred Hershey and Seymour Benzer at Cold Spring Harbor Laboratory, 1953 Symposium.
Seymour Benzer was able to map mutations within one phage gene and correlate the mutations with protein changes. This showed that the DNA sequence of a gene was aligned with protein sequence.
A 1991 Caltech function. (L-R) Seymour Benzer, Rita Levi Montalcini, Ed Lewis and Sydney Brenner.
Sydney Brenner talks about the gene, and Seymour Benzer's contributions in matching the gene to protein sequence.
Sydney Brenner showed that mRNA was the unstable intermediate that carried the message from DNA to the ribosomes.
Herman Muller induces fruit fly mutations. Seymour Benzer works with virus mutants ans proved only one nucleotide change can cause mutation.
