Transfer RNA - Wikipedia
A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length, that serves as the physical link between the mRNA and the amino acid sequence of proteins. tRNA does this by carrying an amino acid to the protein synthetic machinery of a cell as directed by a 3-nucleotide sequence in a messenger ...
Transfer RNA | chemical compound | Britannica.com
Transfer RNA: Transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins. In addition to tRNA there are two other major types of RNA: messenger RNA (mRNA) and ribosomal RNA (rRNA). By 1960 the involvement of tRNAs in the assembly of
Transfer rna | Define Transfer rna at Dictionary.com
Transfer rna definition, a small RNA molecule, consisting of a strand of nucleotides folded into a clover-leaf shape, that picks up an unattached amino acid within the cell cytoplasm and conveys it to the ribosome for protein synthesis. Abbreviation: tRNA See more.
Transfer RNA - definition of transfer RNA by The Free ...
transfer RNA n. Abbr. tRNA Any of a class of RNA molecules that transport amino acids to ribosomes for incorporation into a polypeptide undergoing synthesis. transfer RNA n (Biochemistry) biochem any of several soluble forms of RNA of low molecular weight, each of which transports a specific amino acid to a ribosome during protein synthesis. Sometimes ...
Transfer RNA - an overview | ScienceDirect Topics
Transfer RNA (tRNA) is the smallest of the RNA types (around 4S). Because it serves an adaptor function for amino acids in protein synthesis, at least one unique tRNA exists for each of the 20 amino acids typically found in proteins.
Transfer RNA (tRNA) - Definition, Types and Function ...
tRNA Definition. Transfer RNAs or tRNAs are molecules that act as temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the messenger RNA nucleotide sequence. In this way, they act as the intermediaries between nucleotide and amino acid sequences.
Transfer Rna | Definition of Transfer Rna by Merriam-Webster
Transfer RNA definition is - a relatively small RNA that transfers a particular amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation —called also tRNA.

Mutations in transfer RNA genes reduce the ability of the tRNA to add amino acids to proteins, slowing protein production. Mutations that affect mitochondrial tRNAs impair the ability of mitochondria to provide energy for cells or to control blood sugar levels.
