The group of nucleotides that specifies one amino acid is a code word or condo. The nucleotides of mRNA are arranged as a linear sequence of codons, each London consisting of three successive nitrogenous bases. Three codons UAG, UAA and UGA are the chain stop or termination codons. They do not code for any of the amino acids.
In most organisms AUG codon is the start or initiation codon, They do not code or any of the amino acids.
In most organisms AUG codon is the start or initiation codon, ie, the polypeptide chain starts either with methionine or N-formylmethionine.
