The nucleic acid notation currently in use was first formalized by the International Union of Pure and Applied Chemistry (IUPAC) in 1970. [1] This universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in deoxyribonucleic acids (DNA).
The genetic code is the set of rules ... mRNA three nucleotides at a time. The genetic code is highly similar among all organisms and can be expressed in a simple ...
George Gamow suggested that the genetic code was made of three nucleotides per amino acid. He reasoned that because there are 20 amino acids and only four bases, the coding units could not be single (4 combinations) or pairs (only 16 combinations). Rather, he thought triplets (64 possible combinations) were the coding unit of the genetic code.
However, it is now agreed that the genetic code evolves, [22] resulting in discrepancies in how a codon is translated depending on the genetic source. [ 21 ] [ 22 ] For example, in 1981, it was discovered that the use of codons AUA, UGA, AGA and AGG by the coding system in mammalian mitochondria differed from the universal code. [ 21 ]

An international committee published recommendations for genetic symbols and nomenclature in 1957. [1] The need to develop formal guidelines for human gene names and symbols was recognized in the 1960s and full guidelines were issued in 1979 (Edinburgh Human Genome Meeting). [ 2 ]
