Rating Newest Oldest. Best Answer: A gene is a section of DNA that produces a protein. The gene is composed of a sequence of DNA bases (ACT and G). Each 3 consequtive bases (called a codon) in the gene codes for a single amino acid to be strung onto the protein chain.Codons for cysteine, methionine, proline and tyrosine are TGT, ATG, CCT and TAT respectively.ating Newest Oldest.
