The DNA is ultimately the code for the sequence of amino acids in a polypeptide chain, which forms a protein. Each grouping of three DNA nucleotide bases is a code for a specific amino acid. Scientists know which amino acid each DNA sequence codes for; this is called the genetic code. For example, the DNA nucleotide base sequence CTG codes for the amino acid leucine.
