The three base sequence on a molecule of tRNA which is complementry to a codon on a strand of mRNA.
The recognition of an anticodon to a codon allows an amino acid to be brought to a elongating strand of protein and joined to it.
The first two bases must be completely complementry to the codon to allow hydrogen bonds to form between the base pairs, the third base may be non-complementry or modified base (i.e. inosine) but will still form a hydrogen bond between the anticodon and codon, this is known as the 'Wobble' theory [1].
