Genetic Code: The Genetic Code SparkNotes

WebWith 4 nucleotides in RNA and 3 per codon, there are 64 codons. However, these 64 codons only code for 20 amino acids (or 22 if you include selenocysteine and pyrrolysine ), so many of the amino acids are coded by multiple codons. Is there any hypothesis as to why there are only 22 amino acids and not 64? WebIn fact, there are usually 40 40 to 60 60 different types, depending on the species ^3 3. tRNAs bind to codons inside of the ribosome, where they deliver amino acids for addition to the protein chain.
