tRNA Structure. Transfer RNA (or abbreviated as tRNA) is small RNA molecule, typically between 70 to 90 nucleotides in length. The primary tRNA function is to deliver amino acids required for the process of protein synthesis. Transfer RNAs are carrying amino acids to the ribosome, where the actual protein synthesis takes place.
The function of the ribosome is to bind the tRNA molecules and then move through the ribosome. As the tRNAs are moved, the ribosomeâs configuration brings the amino acids into contact and then severs the bonds between tRNA and amino acid. In a general sense, RNA is acting as an enzyme that catalyzes the reactions that form the amino acid chain.
