How many anticodons?
Much new information on codon composition is becoming available from the sequencing of molecules of DNA and RNA. The "wobble rules" for codon-anticodon pairing are applicable to this information. These rules provide for only 54 anticodons to pair with 61 codons, because the base A is not found in the first position of anticodons.
