Is it a good or bad thing that there are 64 codons and 20 amino acids? defend

Answer: Each codon is responsible for the insertion of the correct amino acid (bound to a tRNA molecule) into the protein being made from the DNA repository. Since only 20 amino acids normally are involved, 64 codons from three nucelotide bases is too many ... There are 64 codons because nature is redundant in protein formation.
