The genetic code is carried by the DNA molecule in most organisms. DNA is the store for hereditary information.
In eukaryotic cells, DNA is found in the cell nucleus, while in prokaryotes it is found in the nucleosome.
The genetic code is the triplets of nucleotides in DNA and RNA that define and direct which amino acid is used in protein synthesis.
The genetic code is expressed in 64 different triplet combinations that code for different amino acids. Three of these triplets are called non sense triplets or codons because they do not code for any amino acid. The rest are sense codons.
