Abstract
THREE general approaches can be used to determine the base sequence of natural messenger ribonucleic acids (mRNAs): (1) the molecular species in question can be purified and sequenced by chemical methods1; (2) purified aminoacyl-tRNAs (which are codon-specific) can be used to deliver labelled amino-acids to particular sites in a protein of known sequence2,3; and (3) the mRNA sequence can be inferred from the pattern of amino-acid substitutions in mutant proteins of known sequence4–6. It has been possible to determine indirectly the RNA sequence which codes for a carboxy-terminal segment of lysozyme4, but no intensive effort seems to have been made to apply the large amount of sequence data7 accumulated on homologous proteins to similar ends.
