Amino acids prior to their incorporation into polypeptide must be attached to a special adaptor molecule. Who proved this and when? Correct Answer Paul C. Zamecnic and Maholon B. Hoagland in 1957

In 1955 Francis H. Crick proposed that prior to the incorporation of amino acids in polypeptide chain they must be attached to an adapter molecule that can interact with the three-nucleotide long coding units of mRNA. This was finally proved in 1957 by Paul C. Zamecnic and Maholon B. Hoagland. They demonstrated that amino acids were carried by the transfer RNAs (tRNA) to the ribosome for its transfer to the growing polypeptide chain.
