Instructions:Fill out each of the blanks with an amino acid from the codon chart - they cannot use the same amino acid twice. There are 21 total amino acids and only 16 squares, so there will be a few not used at all. Your card should be random, and should not look like other cards in the room. Your teacher will call out 3 bases (A, T, G, C), use the codon chart to mark the amino acid that matches the 3 bases. *Use a 4 sided die to randomly call bases!
