anticodon, n. Biochem.|ˌæntɪˈkəʊdɒn|
[f. anti-1 2 + codon n.]
A triplet of nucleotides forming a unit of genetic code in transfer RNA, which binds to a complementary codon in messenger RNA, thereby determining the amino acid carried.
1965Science 19 Mar. 1464/3 There are several possible trinucleotide sequences that might represent the coding triplet or ‘anticodon’ for the transfer of alanine. 1971J. Z. Young Introd. Study Man iii. 57 An alanine transfer RNA molecule might have the anticodon CGA, which is the complement of GCU, one of the triplets that code for alanine. 1982T. M. Devlin Textbk. Biochem. xix. 920 Anticodon sequences in tRNAs of known specificity have been used to confirm the genetic code. Conversely, tRNAs of unknown amino acid specificity have been identified by their anticodons. 1985Sci. Amer. Oct. 56/1 At the opposite end of the tRNA molecule from the amino acid binding site there is a loop containing the ‘anticodon’, a nucleotide triplet that is complementary to a specific mRNA codon.
Hence ˌanticoˈdonic a., of, pertaining to, or involving an anticodon.
1975Bio Systems VII. 32/2 These are of an anticodonic type. 1978Jrnl. Molecular Evol. XI. 199 One can infer a general anticodonic relationship of properties of amino acids and nucleotides. 1980Biochem. & Biophys. Res. Communications XCVI. 491 Further observations showed correlations of properties of amino acids with those of their anticodonic nucleotides. |
