The information needed to direct the synthesis of protein is contained in the mRNA in the form of a genetic code.
The genetic code is the system of nucleotide sequences of mRNA that determines the sequence of amino acids in protein.
Codons are a group of three adjacent bases that specify the amino acids of protein.
Triplet codon - Each amino acid is represented by triplet sequence
There are 64 possible codon sequences.
Three of the 64 possible nucleotide triplets, UAA, UAG and UGA do not code for any amino acids, they are called nonsense codons
The code is degenerate but unambiguous:
As there are 61 codons for 20 amino acids, one amino acid has more than one codon and the code is referred to as degenerate.
Although an amino acid may have more than one codon, each codon specifies only one amino acid. Thus, the genetic code is unambiguous.
