hEnglish - advanced version
1. 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)
(synonym) transfer RNA, acceptor RNA, soluble RNA
(hypernym) ribonucleic acid, RNA
Trna Definition from Science & Technology Dictionaries & Glossaries
BioProcess International™ Glossary
transfer RNA, a small ribonucleic chain (74-93 nucleotides) that transfers amino acids to the ribosome to be placed in the order prescribed by the messenger RNA; tRNA molecules match up with a template strand of mRNA to facilitate formation of a specific sequence of amino acids into linear strands that are later processed in the cell to form proteins.Copyright © 2002 - 2006, BioProcess International™.

Trna Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
A Transfer RNA (abbreviated tRNA and archaically referred to as sRNA abbreviating soluble RNA) is an adaptor molecule composed of RNA, typically 73 to 94 nucleotides in length, that serves as the physical link between the nucleotide sequence of nucleic acids (DNA and RNA) and the amino acid sequence of proteins. It does this by carrying an amino acid to the protein synthetic machinery of a cell (ribosome) as directed by a three-nucleotide sequence (codon) in a messenger RNA (mRNA). As such, tRNAs are a necessary component of protein translation, the biological synthesis of new proteins according to the genetic code.

Terms and Definitions
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.
