Proteins for fun and profit

The production of proteins at an industrial scale using gene sequences offers benefit in terms of costs. The sequences of DNA known as genes can produce many proteins because any subsequence of exons, which are considered to be consisting of amino acid strings, can form a protein. Amino acids are not present in the DNA rather they are present in an alphabet of nucleotides, whose nonoverlapping consecutive triplets are translated to amino acids. Minimizing the number of amino acids produced by the exons minimizes the number of nucleotides in the exons themselves, provided each exon's length is multiple of three.
