The genetic code is a nearly universal language that encodes directions for cells. The language uses DNA nucleotides, arranged in codons of three, to store the blueprints for amino acid chains.
Figure-1- Genetic code is a dictionary that corresponds with sequence of nucleotides and sequence of Amino Acids. Genetic Code-Characteristics (Table-1). 1) Specificity. 1  Genetic code is specific (Unambiguous).  2  A specific codon always codes for the same amino acid.) Non Sense Codons.  1 There are 3 codons out of 64 in genetic code which do not encode for any Amino Acid.  2 These are called termination codons or stop codons or nonsense codons. 3  The stop codons are UAA, UAG, and UGA. 4  They encode no amino acid.
