What actually forms code found in DNA?

The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health ... The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid? will be added next during protein synthesis.

The code in DNA is stored in the four chemical bases (Adenine, guanine, cytosine and thymine) which are found in the genes. These include the information the cell needs to make specific proteins. Each base pair is made from 2 complementary nucleotides (either A+T or G+C) and bound together with hydrogen bonds.
