C. Each combination of nitrogen bases on the mRNA molecule is a codon, which is
a three-letter code for a specific amino acid. The table shows the mRNA codon
for each amino acid. Use the Genetic Code Table to answer the questions.
4. The codon for tryptophan is _____________________.
5. For Leucine, there are ___________________ different codon.
6. The codon GAU is for _____________________________.
7. In a STOP codon, if the second base is G, the first and third bases are _____ and ______.
Given the list of amino acids, determine the sequence of bases in the codon of the mRNA that
codes for these amino acids. Use the table for the Genetic Code.
