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

(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.

an·ti·co·don

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

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.

Because the taurine reaction enhances the interaction of the UUG codon with the anticodon of the tRNA, it stimulates the expression of mitochondria encoded proteins whose mRNAs contain a significant number of UUG codons [16].
The DNAs of wild type and Tyr83 and Trp120 mutant streptavidin and DNA of the tRNA having four-base anticodon and BODIPY-FL-aminophenylalanyl-pdCpA were obtained from laboratory of Professor Hohsaka of Japan Advanced Institute of Science and Technology (JAIST).
Thus, for a new codon and anticodon in translation, the s-y pair is better than the s-z pair.
Rodriguez performed many laborious experiments in which she removed portions of the aminoacyl-tRNA synthetase that interact with the anticodon stem of the transfer RNA, far from the part of the enzyme that binds the amino acid.
Modified uridines with C5-methylene substituents at the first position of the tRNA anticodon stabilize U.G wobble pairing during decoding.
There is a separate tRNA molecule for each of the 20 amino acids, and each one is specific because of a particular anticodon loop, a sequence of three nitrogen bases that read as a complement to the codon at the site of the ribosome-mRNA.
The tRNA molecule has three unpaired nucleotides, which together are called the anticodon sequence; this sequence plays an important role in the formation of the linear array of amino acids that constitute a protein.
The next largest identity region (30/33 bp) was the DHU and anticodon arms of [tRNA.sup.LEU(CUN)].
Incluye cuatro etapas: activacion, en la que se forma el ARN de transferencia (ARNt); iniciacion, cuando el ARNt que contiene metionina, se alinea con el codon iniciador AUG en el ARNm del ribosoma; elongacion, donde cada anticodon del ARNt se adosa a cada codon del ARNm.

A series of three nucleotides is known as a triplet in DNA, a codon in messenger RNA (mRNA), and an anticodon in transfer RNA (tRNA); each will code for a specific amino acid.
