Pronunciation: an′tē-kō′don


The trinucleotide sequence complementary to a codon found in one loop of a tRNA molecule; if a codon is A—G—C, its anticodon is U (or T)—C—G. The complementarity principle arises from Watson-Crick base-pairing, in which A is complementary to U (or T) and G is complementary to C. Sometimes called “nodoc.”
