The unit of the genetic code (the code in which genetic information is carried by DNA and messenger RNA. This information determines the sequence of amino acids in every peotein and thereby controls the nature of all proteins made by the cell. The genetic code is expressed by the sequence of mucleotide basesin the nucleic acid molecule, a unit of three consecutive basis(a codon) coding for each amino acid. The code is translated into protein at the ribosomes. Any changes in the genetic code results in the insertion of incorrect amino acids in a protein chain, giving a neatation) that determines the synthesis of one particular amino acid. Each codon consists of a section of the DNA molecule and the order of the codons along the molecule determines the order of amino acid in each protein made by the cell.
