anticodon

 [an″te-, an″ti-ko´don]
a triplet of nucleotides in transfer RNA that is complementary to the codon in messenger RNA that specifies the amino acid.
 Anticodon. The three nucleotides (shaded) on a transfer RNA bind to a complementary messenger RNA codon. From Dorland's, 2000.

an·ti·co·don

(an'tē-kō'don),
The trinucleotide sequence complementary to a codon found in one loop of a tRNA molecule; for example, 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."

anticodon

/an·ti·co·don/ (-ko´don) a triplet of nucleotides in transfer RNA that is complementary to the codon in messenger RNA which specifies the amino acid.

anticodon

(ăn′tē-kō′dŏn, ăn′tī-)
n.
A sequence of three adjacent nucleotides in transfer RNA that binds to a corresponding codon in messenger RNA and designates a specific amino acid during protein synthesis.

anticodon

[an′tikō′don]
Etymology: Gk, anti + caudex, book
a sequence of three nucleotides found in transfer RNA. Each anticodon pairs complementarily with a specific codon of messenger RNA during protein synthesis and specifies a particular amino acid in the protein. See also genetic code, transcription, translation.

anticodon

A sequence of three nucleotides in transfer RNA complementary to the three nucleotides in a codon on messenger RNA. The anticodon specifies a particular amino acid which is selected and assembled for protein synthesis.

Codon and anticodon interactions are composed of only three base pairings, and thus the unnatural base pairings require thermal stabilities as high as those of the natural base pairs, for the development of an efficient translation system.
After detaching from the DNA, the mRNA is edited and migrates out of the nucleus and into the cytoplasm, where it attaches to a ribosome, specific transfer mRNA is threaded through the ribosome, specific transfer RNAs for each amino acid match at the anticodon loop with the message and place the tRNA amino acid complex in the correct position.
The codon in the mRNA that immediately follows AUG dictates the anticodon sequence and, therefore, which charged tRNA will bind to the ribosome complex.
Salmonella bacteria have devised a tRNA with a four-base anticodon, he says.

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.

The mechanisms by which the 43 S complex interacts with translational initiation sites are poorly understood, except for the requirement for the Met-tRNA anticodon and evidence for involvement of eIF2 (6).
