In Protein Synthesis, 61 Codons Specify the 20 Amino Acids

question 91

Short Answer

In protein synthesis, 61 codons specify the 20 amino acids. Base pairing between the codon and the tRNA anticodon assures that the correct amino acid will be inserted into the nascent polypeptide chain. Why then does the cell require only 32 different tRNAs to recognize 61 different codons?
