poly U gives only phenylalanine, poly A gives only lysine, therefore UUU codes for phenylalanine and AAA for lysine and therefore one triplet can only code for one amino acid. In the mixture, more U is linked to higher % of cysteine and valine, therefore UGU and GUU are likely triplets. There are more combinations of U and G in a triplet than four, therefore one amino acid could have more than one code
