A DNA molecule is shown here.

A nucleotide is represented by one of the letters \(\{a, t,

c, g\}\). A codon is defined to be a triplet of nucleotides. The order of the nucleotides in a codon is significant, and the nucleotides can be repeated. These codons are important in determining how DNA is transformed into protein. How many different codons are possible?
