…Transfer RNA (tRNA) has the ability to convert the sequence of codons on an mRNA molecule into a sequence of amino acids. There are many different types of tRNAs in cells that correspond to each codon. Each tRNA molecule has a specific amino acid attached to one end, and at another point on the molecule, it has a triplet of bases (anticodon) that binds to the mRNA codon in a complementary manner. The codon and anticodon bind in the opposite direction. … From [Genetic Information]...A unit of three base sequences on mRNA specifies one amino acid, and this unit of three bases is called a codon. tRNA is involved in the process of decoding a codon into an amino acid, and decoding is achieved when the three bases in the anticodon of the tRNA molecule complement each other with the three bases of the codon (see the transfer RNA section in the RNA entry). In addition to the base sequence that specifies the amino acid sequence, mRNA molecules usually have extra base sequences before and after it. ... From [Protein synthesis (protein synthesis)]…Amino acids are covalently bound to transfer RNA (tRNA) and transported to the ribosome. Each amino acid corresponds to a different tRNA molecule, and the tRNA molecule has an anticodon that decodes the codons in the mRNA. The amino acids are transferred from the tRNA to the peptide chain on the ribosome in order according to the order of the codons on the mRNA (translation of genetic information). … *Some of the terminology explanations that mention "anticodon" are listed below.

…mRNA分子上のコドンの配列をアミノ酸配列に変換する能力をもつ転移RNA(tRNA)は,各コドンに対応して多種類のものが細胞内に存在している。このtRNA分子はそれぞれ特異的なアミノ酸を一端に結合し,また分子の別の個所に,mRNAコドンに相補的に結合する三つ組塩基配列(アンチコドンanticodon)をもっている。コドンとアンチコドンは逆向きに結合する。… 【遺伝情報】より…mRNA上の3個の塩基配列が単位となって,1個のアミノ酸を指定しているが,この3塩基からなる単位をコドンcodonと呼ぶ。コドンをアミノ酸に解読する過程には,tRNAが関与し,tRNA分子のアンチコドンanticodon部位の3塩基が,コドンの3塩基と相補的な対合をすることで解読が成立する(〈RNA〉の項目の転移RNAの部分を参照)。 mRNA分子は,アミノ酸の配列を指定する塩基配列以外にも,その前後に余分な塩基配列をもつのが通例である。… 【タンパク質合成(蛋白質合成)】より…アミノ酸は転移RNA(tRNAと略記)に共有結合した型で,リボソームへと運ばれる。おのおののアミノ酸種には異なったtRNA分子が対応しており,tRNA分子上にはmRNAのコドンを解読するアンチコドンanticodonという部位が存在する。mRNA上のコドンの順番に従って,アミノ酸はリボソーム上で,tRNAからペプチド鎖へと順次引き渡されていく(遺伝情報の翻訳)。… ※「anticodon」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
