How many amino acids are shown on the section of normal DNA?

The number of amino acids represented by a section of DNA depends on the length of the DNA sequence and its reading frame. Each amino acid is encoded by a sequence of three nucleotides, known as a codon. Therefore, to determine the number of amino acids, you divide the total number of nucleotides in the DNA section by three. For example, a DNA sequence with 300 nucleotides would code for 100 amino acids.
