Anticodon
An anticodon is a unit made up of three nucleotides that correspond to the three bases of the codon the tRNA reads. Each tRNA contains a specific anticodon triplet sequence that can base-pair to one or more codons for an amino acid.

At one end of the tRNAs three contiguous nucleotides, the anticodon, specifically base pair with only a specific subset of codon triplets. The opposite ends have a place for covalent attachment of an amino acyl residue.

Each kind of tRNA has a sequence of 3 unpaired nucleotides — the anticodon — which can bind, following the rules of base pairing, to the complementary triplet of nucleotides — the codon — in a messenger RNA (mRNA) molecule.

Notice that the 3-letter anticodon on the tRNA molecule matches the 3-letter code (called a codon) in the mRNA. The tRNA with the anticodon "UAC" bonds with methionine. It always transports methionine.

These variable codes for amino acids are possible because of modified bases in the first base of the anticodon, and the basepair formed is called a wobble base pair. The modified bases include inosine and the U-G basepair.
