A sequence of three DNA nucleotide bases makes up a triplet. This triplet codes for one of 20 specific amino acids. The genetic code is universal because it is the same in all living organisms. For example, AAG codes for Lysine in all living organisms. It is non-overlapping because each triplet within the sequence is read separately and one after the other.For example, CCAAAGAGC is read CCA AAG AGC. It would NOT be read CCA AAA AGA AGCIt is degenerate because more than one triplet can code for the same amino acid. This makes sense as there are 64 possible triplets but only 20 possible amino acids.For example, GGU and GGA both code for Glycine
