The genetic code is the relationship between DNA base sequences and the amino acid sequence in proteins. The genetic code features include: 1  amino acids are encoded by three nucleotides. 2  it is non-overlapping. 3  it has no punctuation (alternatively, the stop codons could be viewed as a period or full stop.).
