within the ribosome, a form of RNA that transports amino acids into the positions coded in the mRNA.
( tRNA) A small ribonucleic acid molecule that contains an anticodon, a binding site for a specific amino acid, and recognition sites for interaction with the ribosome and the enzyme that links it to its specific amino acid.
RNA molecules that transfer amino acids to the ribosomes. The tRNA anticodon sequence is complementary to the codon of mRNA.
A category of relatively small RNA molecules (about 75 nucleotides). Each kind of transfer RNA is able to accept a particular activated amino acid from its specific activating enzyme, after which the amino acid is added to a growing polypeptide chain.
An RNA molecule used in protein synthesis as a link helping to convert messenger RNA into amino acids.
pieces of RNA which are small and are found in all cells. Each different tRNA carries a specific amino acid to the ribosomes in the cell so that protein synthesis can take place. Each piece of tRNA lines up with a specific piece of messenger RNA to ensure that the amino acids are arranged in the correct sequence.
small RNA molecules of 70-90 ribonucleotides that recognize and transfer a specific amino acid for protein synthesis.
a small RNA molecule that "translates" a codon in mRNA by bringing in its corresponding amino acid during protein synthesis.
links with a specific amino acid and recognizes the correct mRNA codon for the amino acid through base pairing the codon with the anticodon (a three nucleotide sequence).
An RNA class characterized by a three-nucleotide sequence (the anticodon) that is complementary to a three-nucleotide sequence in mRNA (the codon). Attachment of an amino acid forms the active aminoacyl tRNA which functions as a ribosomal adaptor during t
The RNA that becomes attached to an amino acid and guides it to the correct position on the ribosome for protein synthesis; there is at least one tRNA molecule for each amino acid.
Adaptor molecules which translate the triplet code from the mRNA sequence into the corresponding chain of amino acids. tRNAs are short (about 74-95 bases), single-stranded RNA molecules that contain a high proportion of modified nucleosides. When drawn in two-dimensions, tRNAs can be folded into a characteristic cloverleaf structure with three stem-loop structures. The anticodon at the base of the second loop region. A specific amino acid is are added to the 3' end of each tRNA by a specific aminoacyl tRNA synthetase. The aminoacylated tRNA binds to the ribosome-mRNA complex via interactions with the ribosome and, if the anticodon in the tRNA is properly paired with the complementary bases in the codon at that position, the amino acyl group is transferred to the growing polypeptide chain.
trans, across + ferre, to bear or carry] An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and recognizing the appropriate codons in the mRNA.
The RNA that carries amino acids to the ribosome to be placed in the sequence prescribed by the messenger RNA.
short-chain RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)

tRNA) A type of RNA that carries amino acids to ribosomes for the purpose of constructing a protein.
RNA molecules that bind to amino acids and carry them to the ribosomes where proteins are made.
RNA molecules which transfer specific amino acids to the messenger RNA so that the polypeptide it encodes can be synthesized.

Small RNA molecules that carry specific amino acids to the ribosome during protein synthesis.
An RNA molecule serving as transporter of a defined kind of amino acid in protein synthesis and bearing a triplet of bases, or anticodon, that, when the molecule is strategically situated on the ribosome surface, is specifically recognized by a messenger-RNA codon. ~ See Also: Anticodon, Base pairing, Codon, Messenger RNA, Protein, Ribosome, Wobble.
RNA molecules that carry amino acids to sites on ribosomes where proteins are synthesized.
(tRNA) A class of RNA that carries amino acids into ribosomes and bonds with mRNA for protein production.
(tRNA) RNA that transports amino acids to the ribosomes, where the amino acids are assembled into proteins.
A class of RNA having structures with triplet nucleotide sequences that are complementary to the triplet nucleotide coding sequences of mRNA. The role of tRNAs in protein synthesis is to bond with amino acids and transfer them to the ribosomes, where proteins are assembled according to the genetic code carried by mRNA.
The class of small RNA molecules that transfer single amino acids to the polyribosome complex during protein synthesis.
a RNA molecule that interprets mRNA nucleotide codons and picks up the specific amino acids which the mRNA code for.
Small RNA molecule that positions amino acids in the correct order during protein synthesis.
Specialized RNA which transfers single amino acids to a growing protein chain. tRNA has a complementary codon to the codon on the mRNA.

Transfer RNA (abbreviated tRNA) is a small RNA chain (73-93 nucleotides) that transfers a specific amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation. It has a site for amino acid attachment and a three-base region called the anticodon that recognizes the corresponding three-base codon region on m RNA via complementary base pairing. Each type of tRNA molecule can be attached to only one type of amino acid, but because the genetic code is degenerate - that is, it contains multiple codons that specify the same amino acid - multiple types of tRNA molecules bearing different anticodons may carry the same amino acid.
