How do 64 codons code for only 20 amino acids?
proteins is the sequence of four different nucleotides that is used to convey information for combination of 20 amino acids to form polypeptide chain. Each amino acid is represented by three nucleotides (triplet). This is true. There are only 16 different doublets of four nucleotides (42) and that 64 (43) triplets. These are 64 amino acids. It means that more than one codon can code for same amino acids.
