transfer RNA
Sign in to saveadaptor molecule composed of RNA, typically 76–90 nucleotides, that carries amino acids to the ribosome as directed by codons in mRNA
AI overview
Transfer RNA is a small molecule made of RNA that acts like a messenger's assistant in your cells, picking up amino acids and delivering them to the ribosome based on instructions from messenger RNA. It matters because without it, your cells couldn't translate the genetic code into the proteins that your body needs to function.

Article
Transfer ribonucleic acid (tRNA), formerly referred to as soluble ribonucleic acid (sRNA), is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes). In a cell, it provides the physical link between the genetic code in messenger RNA (mRNA) and the amino acid sequence of proteins, carrying the correct sequence of amino acids to be combined by the protein-synthesizing machinery, the ribosome. Each three-nucleotide codon in mRNA is complemented by a three-nucleotide anticodon in tRNA. As such, tRNAs are a necessary component of translation, the biological synthesis of new proteins in accordance with the genetic code.
