The genetic code establishes the relationship between all 64 possible arrangements of the four nucleotide bases contained in either DNA (A, T, G and C) or RNA (A, U, G and C) and the 20 amino acids that are used to construct proteins. The historical events that contributed to the deciphering of the genetic code led to the development of the field of molecular biology.
