Alan Garen

Alan Garen was an American geneticist who co-discovered suppressor mutations for tRNA. The Garen lab also showed that certain triplet codons (5'-UAG, 5'-UAA, and 5'-UGA) failed to bind amino acids. Thus, the Garen lab and Brenner labs are both credited with discovery of the stop codons of the genetic code.

Garen was a professor at Yale University between 1963 and 2021. He was a member of the National Academy of Sciences and the American Academy of Arts and Sciences.
