Anticodon

|
An anticodon is a unit made up of three nucleotides which play an important role in various DNA cycles, including RNA translation. It is, specifically, the group of nucleotides on a strand of tRNA that is complementary to specific codons on a strand of mRNA. See also protein synthesis.
Frequently, the third nucleotide of the anticodon is one of two not found on mRNA: inosine and pseudoridine. Consequently, the link between an anticodon and an mRNA codon is less strict than those links in DNA and RNA-DNA hybrids.
