The triplet sequence of nucleotide bases in the DNA chain, as reflected in messenger ribonucleic acid (mRNA) , that determines the sequence of amino acids during protein synthesis.

Whereas isotopes are the various forms of a single element (hence, are a family of nuclides) and all have the same atomic number and number of protons, nuclides comprise all of the isotopic forms of all of the elements.
