(redirected from anticodons)
Also found in: Dictionary, Medical.


A three-nucleotide sequence in transfer RNA that complements the codon in messenger RNA.



part of the transfer ribonucleic acid or tRNA (in Russian, transport RNA or t-RNA), consisting of three unpaired (free bond) nucleotides. This section is specifically paired with the codon of messenger RNA or mRNA (in Russian, information RNA or i-RNA), which assures the proper arrangement of each amino acid during protein synthesis.

The primary features of the sheep mitogenome, including gene structure, gene arrangement, initiation codon, termination codon, and anticodon, were described and compared among the 3 types of sheep.
Crick gave flexible rules for pairing the third base of the codon with the first base of the anticodon, to the extent that a single tRNA type would be able to recognize up to three codons.
However, Meyer either avoids, or is simply unaware of, a significant amount of research in this area that has demonstrated chemical interactions between amino acids and their cognate anticodons or codons.
