Johannes Heinrich Matthaei (born 4 May 1929) is a German biochemist. He is best known for his unique contribution to solving the genetic code on 15 May 1961. Whilst a post-doctoral visitor in the laboratory of Marshall Warren Nirenberg at the NIH in Bethesda, Maryland, he discovered that a synthetic RNA polynucleotide, composed of a repeating uridylic acid residue, coded for a polypeptide chain encoding just one kind of amino acid, phenylalanine. In scientific terms, he discovered that polyU codes for polyphenylalanine and hence the coding unit for this amino acid is composed of a series of Us or, as we now know the genetic code is read in triplets, the codon for phenylalanine is UUU. This single experiment opened the way to the solution of the genetic code. It was for this and later work
