一般描述
Transfer ribonucleic acid (tRNA) is a non-coding RNA. It is approximately 70-100 base pair long. It has a cloverleaf shaped secondary structure. It has three or four arms and a stem structure. It has minor bases like pseudouridine, dihydrouridine and methylated bases in its structure. It has a binding site for triplet nucleotide sequence and for amino acids.

生化/生理作用
Transfer ribonucleic acid (tRNA) plays a major role in translation, a key step in protein synthesis. It decodes mRNA into protein. There are about 40-60 different tRNAs in a eukaryotic cell and fewer in bacteria. This depends on the degeneracy of the amino acid code. Each amino acid has a specific tRNA. tRNAs are charged with specific amino acid and carries them to the site of protein synthesis. It binds to the ribosome and directs the amino acid to the growing polypeptide chain. It also functions as a regulator of various biological processes. Mutations associated with tRNA is implicated in human diseases.
